Features of the Cisco 12008 Router The power supplies of both types are hot-swappable, load-sharing units. In a system equipped with two AC-input power supplies or two DC-input power supplies, if one of the units fails or if the power source for one of the units fails, the surviving power supply continues to operate to sustain normal router operations. Note The Cisco 12008 does not support a mixture of AC-input and DC-input power supplies.
Overview of the Cisco 12008 Separately orderable documents called configuration notes or replacement instructions are available for each of the FRUs described previously. These documents provide installation, removal, replacement, and configuration instructions for the FRUs.

Overview of the Cisco 12008 Router Enclosure The outer shell of the Cisco 12008 is a rigid, sheet metal structure with the following dimensions: • • • Width—17.4 inches (44.6 cm) Depth—21.2 inches (54.4 cm) Height— 24.8 inches (63.6 cm) This enclosure, which houses all of the router’s internal components, can be mounted in a telco rack or a four-post equipment rack, or the enclosure can be used as a freestanding unit. The design of the enclosure permits front accessibility of all router components.
Overview of the Cisco 12008 The cable management tray enables you to route the line card interface cables to or from the system through the left side of the tray, keeping the cables organized, out of the way, and free of kinks or sharp bends. You direct the cables down to the individual ports on each line card, gauging cable length appropriately to minimize slack in the cable before connecting it to a given port.
Overview of the Cisco 12008 • Vertical cable-management bracket (one per line card)—This bracket is attached to a line card by means of captive installation screws at the top and bottom of the bracket. Once an interface cable is connected to its intended line card port, you loop the cable through the cable keeper clip nearest the port of connection and seat the cable in the bottom of the bracket raceway.
Overview of the Cisco 12008 If an overtemperature condition or a fan failure is detected within the router, the master MBus module on the RP directs the MBus module on the clock and scheduler card (CSC) to increase the operating voltage being delivered to the fan tray, causing the card cage fans to run at “maximum” speed. This increases the volume of cooling air flowing through the router.
Overview of the Cisco 12008 AC-Input and DC-Input Power Supplies The Cisco 12008 router can be configured to operate with AC source power or DC source power. You can install one or two AC-input power supplies or one or two DC-input power supplies in the power supply bays located in the right side of the router enclosure (see Figure 1-2). A single power supply of either type is the standard router configuration. In such a configuration, it is recommended that you install the power supply in the lower bay.

Overview of the Cisco 12008 Rotary Power Switch The rotary power switch on the DC-input power supply performs the same functions as those described in the section entitled “Rotary Power Switch” on page 18 for the AC-input power supply. Circuit Breaker Alarm Terminal Block The onboard power supply circuit breaker actuated by the rotary power switch on the DCinput power supply incorporates an auxiliary switch that is mechanically linked to (but electrically isolated from) the power supply circuit breaker.
Overview of the Cisco 12008 The three contacts on the alarm terminal block are labeled as follows: • COM (Common)—This contact is common to both the Normally Open (NO) and the Normally Closed (NC) contacts. • NO (Normally Open)—These contacts on the alarm terminal block are open as long as no overcurrent condition is detected in the power supply. When the power supply circuit breaker is tripped during an overcurrent condition, these contacts are closed.
Overview of the Cisco 12008 The power specifications for the DC-input power supplies, as well as the specifications of the source DC power cables for use with the Cisco 12008 router, are presented in the section entitled “DC-Powered Systems” on page 16 in Chapter 2.
Overview of the Cisco 12008 Although you can install a line card in slot 0, the recommended convention is for the RP to occupy this slot.
Overview of the Cisco 12008 A Cisco 12008 that is configured for full redundancy contains the following cards in the upper card cage: • • • Two RPs Two CSCs As many as six Cisco 12000 series line cards of any type and any combination The following sections briefly describe the cards that you can use to populate the upper card cage. Gigabit Route Processor Each Cisco 12008 GSR has one main system (or route) processor.
Overview of the Cisco 12008 • • Asynchronous serial ports Ethernet port If you have a PRP, see the Performance Route Processor section. The faceplate of the GRP is shown in Figure 1-9. -1 OT SL -0 OT SL 5 -4 RJ LL CO RX T SE RE CO NS OL E T EC EJ K LIN TX H10548 GRP Faceplate (Horizontal Orientation Shown) AU X Figure 1-9 MII GIGABIT ROUTE PROCESSOR It is recommended that you install the GRP in the left-most slot (slot 0) in the upper card cage.
Overview of the Cisco 12008 The GRP communicates with the line cards either through the switch fabric or through a maintenance bus (MBus). The switch fabric connection is the main data path for routing table distribution as well as for packets that are sent between the line cards and the GRP. The MBus connection allows the GRP to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations.
Overview of the Cisco 12008 The Cisco 12008 supports downloadable system software for most Cisco IOS software upgrades, enabling you to remotely download, store, and boot from a new Cisco IOS software image. GRP Memory Components Table 1-2 lists the memory components on the GRP. Figure 1-10 shows the location of the two DRAM SIMMs and the Flash SIMM on the GRP.

Overview of the Cisco 12008 DRAM The extended data output (EDO) dynamic random-access memory (DRAM) on the GRP stores routing tables, protocols, and network accounting applications, and runs the Cisco IOS software. The standard (default) GRP DRAM configuration is 64 megabytes (MB) of EDO DRAM, which you can increase up to 256 MB through DRAM upgrades. The Cisco IOS software runs from within GRP DRAM. Two DRAM DIMM sockets are incorporated into the GRP, as shown in Figure 1-10.
Overview of the Cisco 12008 NVRAM The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 512-KB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of five years. NVRAM is not user configurable or field-upgradeable.
Overview of the Cisco 12008 — Two RJ-45 or MII Ethernet port select LEDs: these LEDs, when on, identify which one of the two Ethernet connections you selected. When the RJ-45 port is selected, its LED is on and the MII LED is off. When the MII port is selected, its LED is on and the RJ-45 LED is off. • The alphanumeric displays are organized as two rows of four characters each. The displays’ content is controlled by the MBus module software.
Overview of the Cisco 12008 Caution To prevent system problems or loss of data, use the soft reset switch only at the advice of Cisco service personnel. PCMCIA Slots The GRP has two PCMCIA slots available. Either slot can support a Flash memory card or an input/output (I/O) device as long as the device requires only +5 VDC. The GRP supports Type 1 and Type 2 devices; it does not support +3.3 VDC PCMCIA devices. Each PCMCIA slot has an ejector button for ejecting a PCMCIA card from the slot.
Overview of the Cisco 12008 Note The RJ-45 and MII receptacles on the GRP faceplate represent two physical connection options for one Ethernet interface; therefore, you can use either the MDI RJ-45 connection or the MII connection, but not both simultaneously. Performance Route Processor Each Cisco 12012 GSR has one main system (or route) processor. The route processor (RP) processes the network routing protocols and distributes updates to the Cisco Express Forwarding (CEF) tables on the line cards.
Overview of the Cisco 12008 Figure 1-11 shows the front panel view of the PRP.
Overview of the Cisco 12008 • Up to 2 GB of SDRAM on two PC133-compliant, dual in-line memory modules (DIMMs). 512 MB of SDRAM is the default shipping configuration. SDRAM is field replaceable. • Two MB of SRAM for secondary CPU cache memory functions. SRAM is not user configurable or field replaceable. • • Two MB of NVRAM. NVRAM is not user configurable or field replaceable. • Air-temperature sensors for environmental monitoring.

Overview of the Cisco 12008 Note If a single DIMM module is installed, it must be placed in bank 1 (U15). SDRAM SDRAM stores routing tables, protocols, and network accounting applications, and runs the Cisco IOS software. The default PRP configuration includes 512 MB of error checking and correction (ECC) SDRAM. DIMM upgrades of 512 MB and 1 GB are available. You cannot mix memory sizes. If two DIMMS are installed, they must be the same memory size.
Overview of the Cisco 12008 Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash memory (called bootflash) contains the Cisco IOS boot image, and the Flash disk contains the Cisco IOS software image. A 64-MB ATA Flash disk ships by default with the PRP. Table 1-5 lists the supported Flash disk sizes and their Cisco product numbers.
Overview of the Cisco 12008 The alphanumeric display LEDs are organized as two rows of four characters each and are located at one end of the card. These LEDs provide system status and error messages that are displayed during and after the boot process. The boot process and the content displayed are controlled by the PRPs MBus module software. At the end of the boot process, the LEDs are controlled by the Cisco IOS software (via the MBus), and the content displayed is designated by the Cisco IOS software.
Overview of the Cisco 12008 Access to the soft reset switch is through a small opening in the PRP faceplate. To press the switch, you must insert a paper clip or similar small pointed object into the opening. Flash Disk Slots The PRP includes two Flash disk (PCMCIA) slots. Either slot can support an ATA Flash disk or a Type 1 or Type 2 linear Flash memory card. The PRP ships by default with one 64-MB ATA Flash disk. Note The PRP only supports +5VDC Flash disk devices. It does not support +3.
Overview of the Cisco 12008 Note The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable. Switch Fabric of the Cisco 12008 The heart of the Cisco 12008 is the switch fabric circuitry, which provides synchronized gigabit speed interconnections between the line cards and the RP.
Overview of the Cisco 12008 Table 1-6 Switch Fabric Configurations Switch Fabric Bandwidth Number of CSCs Number of SFCs Planes of Switch Fabric OC-12 nonredundant 11 0 1 OC-12 redundant 2 0 2 OC-48 nonredundant 1 3 4 OC-48 redundant 2 3 5 1. A CSC is a required router component. A minimally configured router (one with a single CSC and no SFCs) supports an OC-12 data rate, but provides no redundancy of CSC functions.
Overview of the Cisco 12008 As a multi-function board, the CSC provides the following system services: • Provides one plane of switch fabric for the router (see the section below entitled “Switch Fabric in the Cisco 12008”). • Serves as a switch fabric controller card for the router (see the section below entitled “Switch Fabric Controller Functions of the CSC”).
Overview of the Cisco 12008 Table 1-7 Switch Planes Provided by Switch Cards Switch Card Type Availability Number of Switch Planes One CSC Standard 1 A single CSC supports an OC-12 data rate for the router, but provides no redundancy in the router’s switch fabric. Second CSC Optional 1 A second CSC supports an OC-12 data rate for the router and also provides a redundant plane of switch fabric.

Overview of the Cisco 12008 In a redundant CSC configuration, the phase of the master clock generator on one card is synchronized with that of the other card. If either clock drifts, the master clock generators on both cards remain tightly aligned. Should one of the CSCs fail, the phase lock between the two master clock sources is aborted within nanoseconds, enabling the surviving CSC clock to remain stable and take over master clock duties.
Overview of the Cisco 12008 This single switch plane of the CSC can be used alone in a minimum router configuration, or it can be used in combination with another CSC and the three optional SFCs for full switching redundancy. In the latter case, the per line-card slot bandwidth of the router is increased from an OC-12 rate to an OC-48 rate, and the second CSC provides redundancy.

Overview of the Cisco 12008 — DB-25 alarm contact connector—A female DB-25 D-sub connector incorporated into the CSC faceplate enables you to attach an external alarm monitoring facility to the router, thus supporting a telco style of handling alarm conditions in the router. The alarm signals sent to this DB-25 connector are identical in function to those sent to the system LEDs on the CSC faceplate (see the following section entitled “System Alarm LEDS”).
Overview of the Cisco 12008 In a system equipped with two CSCs, pressing the ACO/LT button on one CSC is equivalent to pressing this button on either CSC or both CSCs. — System alarm LEDs—Three system LEDs, labeled critical, major, and minor, are incorporated into the CSC faceplate (see Figure 1-14) to signal the existence of alarm conditions detected in the router by the system’s environmental monitoring circuitry.
Overview of the Cisco 12008 If the FAIL LED goes on, it indicates that one of the three SFCs in the lower card cage has failed. To determine which of the SFCs has failed, you must remove the air filter assembly and examine the status of the LEDs on each SFC. Two side-by-side LEDS behind a vertical tab near the center of the SFC (see Figure 1-15) indicate the operational status of the card.
Overview of the Cisco 12008 • Fan tray power—The Cisco 12008 router contains two fan trays (see Figure 1-2). Control of fan power is initiated at system startup, with the fans running at a slow rate for normal operations. Such operation minimizes fan noise, wear, and power consumption. A DC-DC converter on the CSC provides +20 VDC for slow fan operation and +25 VDC for fast fan operation when an overtemperature condition is sensed in the router.
Overview of the Cisco 12008 These cards provide the interfaces to the router’s external physical media. They exchange packet data with each other by way of the router’s switch fabric. Caution Any unoccupied slot in the upper card cage must have a blank filler panel installed for EMI compliance and to ensure proper air flow through the router enclosure.

Overview of the Cisco 12008 Each Quad OC-3c/STM-1c POS line card incorporates the following major components: • Transceivers—The single-mode intermediate reach transceiver provides a full-duplex, 155-Mbps, 1300-nm, laser-based SONET/SDH-compliant interface. The multimode transceiver provides a full-duplex, 155-Mbps, 1300-nm, LED-based SONET/SDH compliant interface. The SONET specification for fiber-optic transmission defines two types of fiber: single mode and multimode.
Overview of the Cisco 12008 Once the forwarding decision has been made, the silicon queuing engine is notified by the forwarding processor, and the silicon queuing engine places the packet in the proper queue. This partitioning between the Layer 2 switching accelerator and the forwarding processor blends the high throughput of hardware-accelerated forwarding with the flexibility of software-based routing. • Silicon queuing engine—Each line card has two silicon queuing engines: receive and transmit.
Overview of the Cisco 12008 • Cisco Express Forwarding (CEF) memory table—Each line card maintains CEF tables.

CHAPTER 2 Preparing for Installation This chapter provides specific information about preparing your site for installation of the Cisco 12008 router. Included are safety guidelines, specific preparatory information, and tools and parts required to ensure successful installation of your router. The shipping package for Cisco 12000 series routers is engineered to reduce the potential of product damage associated with routine material handling experienced during shipment.
Safety Recommendations • • Checking the Contents of the Shipping Container Using a Site Log Before attempting to install your router, consider the power and cabling requirements that must be satisfied, the equipment that you will need to install the router, and the environmental conditions that your site must meet. Safety Recommendations The following guidelines are provided to help ensure your safety and to protect the equipment.
Safety Recommendations • Review the safety warnings contained in the document entitled Regulatory Compliance and Safety Information for the Cisco 12000 Series Gigabit Switch Routers (Document Number 78-4347-02). This document accompanied the shipment of your Cisco 12008 router; familiarize yourself with its contents before attempting to install, configure, or maintain the router.
Safety Recommendations • Enlist the assistance of a second person when lifting the router; do not attempt to lift the router by yourself. • • Secure your footing when lifting the router; balance the lifted weight between your feet. • Keep your back straight and lift with your legs. If you must bend down to lift the router, bend at your knees, rather than your waist, to reduce the strain on your lower back. • Always disconnect all external cables before lifting or moving the router.
Safety Recommendations • Do not perform any action that creates a potential hazard to personnel or makes the equipment unsafe. • • Never install equipment that appears to be damaged. Carefully examine your work area for possible hazards, such as moist floors, ungrounded power extension cables, and missing safety grounds.
Safety Recommendations • Always place a card component side up on an antistatic surface, in an antistatic card rack, or in a static-shielding bag. If you are returning a card to the factory, immediately place it in a static-shielding bag. • Use the ejector levers to properly seat the card connectors in the backplane when you are installing line cards or the RP; tighten both captive installation screws on the card.
Site Requirements Guidelines Site Requirements Guidelines Before installing the Cisco 12008 router, review the guidelines presented in the following sections. Rack-Mounting Guidelines Before installing the Cisco 12008 in a telco-style or 19-inch equipment rack, consider the following rack-mounting guidelines: • Install the router in an enclosed rack only if the rack has adequate ventilation or an exhaust fan; install the router in an open rack whenever possible.
Site Requirements Guidelines • If you mount the router in a telco-style rack, ensure that the rack is bolted to the floor. Ensure that the weight of the router does not make the rack unstable. Some telco-style racks are also secured to ceiling brackets, if necessary, due to the weight of equipment in the rack. Make sure that the rack you are using to install the router is secured to the building structure.

Site Requirements Guidelines Power Guidelines The Cisco 12008 router can be configured with either AC-input or DC-input power supplies. Note Combining an AC-input power supply with a DC-input power supply in the same router is not allowed. A minimally configured router has one AC-input power supply or one DC-input power supply. Site requirements for the power supplies differ, depending on the type of source voltage required for the installed power supply(ies).
Site Requirements Guidelines • Provide a dedicated power source for each AC-input power supply installed in the router. • • Install an uninterruptible power source for your site, if possible. Install proper site grounding facilities to guard against damage from lightning or power surges. For a listing of the electrical specifications for the AC-input power supply, see Table 1-9 in Chapter 1. Figure 2-5 lists the source AC power cords available for the Cisco 12008.
Site Requirements Guidelines Table 2-1 AC Power Cord International Options Label Description Product Number United States 208 VAC, 60 Hz AC power cord CAB-GSR12-US= Australian 240 VAC, 50 Hz AC power cord CAB-GSR12-AU= European 230 VAC, 50 Hz AC power cord CAB-GSR12-EU= Italian 220 VAC, 50 Hz AC power cord CAB-GSR12-IT= United Kingdom 240 VAC, 50 Hz AC power cord CAB-GSR12-UK= Note All source AC power cords are 14 feet (4.27 m) in length.
Site Requirements Guidelines Each set of power terminals on the DC-input power supply faceplate consists of two 6-mm, metric-threaded, nickel-plated brass studs centered 0.625 inch apart. The earth ground studs extend 0.52 inch (13.2 mm) above the power supply faceplate; the set of positive (+) and negative (–) studs extend 0.9 inch (22.9 mm) above the faceplate. The nickel plating on the studs enhance their conductivity and ensure corrosion resistance.
System Ground Connection Guidelines System Ground Connection Guidelines Before connecting power to or turning on the Cisco 12008, be sure to provide an adequate ground connection for your system. Two system (earth) grounding holes are provided on each side panel of the router enclosure, approximately 3 inches from the bottom rear of the panel (Figure 2-7).

Site Wiring Guidelines EMI Considerations When wires are run for any significant distance in an electromagnetic field, interference can occur between the electromagnetic field and the signals on the wires. Be aware of the following points: • Bad site wiring practices can result in the emanation of radio frequency interference (RFI) within the site. • Strong EMI, especially that caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the router.
Site Wiring Guidelines Synchronous Optical Network Connection Guidelines The Synchronous Optical Network (SONET) specification for fiber-optic transmission defines two types of fiber: • • Single mode Multimode Data transmission in either mode occurs by means of bundles of light rays that enter the fiber at a particular angle. Single-mode fiber allows only one mode of light to propagate through the fiber; multimode fiber allows multiple modes of light to propagate through the fiber.
Site Wiring Guidelines Power Budget To design an efficient optical data link, you must evaluate the power budget. The power budget represents the amount of light that must be available to overcome attenuation in the optical link and to exceed the minimum power required by the receiver to operate within specifications. Proper operation of an optical data link depends on modulated light reaching the receiver with enough power to be correctly demodulated.
Site Wiring Guidelines Approximating the Line Card Power Margin The LED used for a multimode transmission light source creates multiple propagation paths of light, with each path having a different path length and time requirement to cross the optical fiber. This causes signal dispersion (smear). Higher order loss (HOL) results from light from the LED entering the fiber and being radiated into the fiber cladding.
Site Wiring Guidelines Subtracting the data link loss from the power budget should produce a result greater than zero. If a result is less than zero, you may have insufficient power for receiver operation. For SONET line cards, the signal must meet the signal requirements listed in Table 2-6. Table 2-6 Line Card SONET Signal Requirements Characteristic Single-Mode Multimode Minimum transmitter power (PT) –18.5 –15 Minimum receiver sensitivity (PR) –30 –28 Power Budget (PB) –11.
Site Wiring Guidelines Multimode Power Budget Example of Dispersion Limit Below is a multimode power budget example based on the same parameters as in the previous example, but with a multimode link distance of 4 km: PB = 13 dB – 4 km (1.0 dB/km) – 4 (0.5 dB) – 3 (0.5 dB) – 0.5 dB (HOL) – 1 dB (CRM) PB = 13 dB – 4 dB – 2 dB – 1.5 dB – 0.
Installation Tools Required Estimate the power budget as follows: PB = 11.5 dB – 11 km (0.5 dB/km) – 10 (0.5 dB) PB = 11.5 dB – 5.5 dB – 5 dB PB = 1 dB The resulting power budget (PB) value of 1 dB indicates that this link would have sufficient power for transmission and would not exceed the maximum receiver input power. Using Statistics to Estimate the Power Budget Statistical models are more accurate in determining the power budget than “worst-case” methods.
Unpacking the Cisco 12008 • 9/16-inch wrench (open-end or socket)—for removing the lag bolts from the router shipping pallet • • Wire cutters Pliers Unpacking the Cisco 12008 To unpack your Cisco 12008, use the instructions in the document entitled Cisco 12008 Gigabit Switch Router System Packing and Unpacking Instructions, which was shipped with the router.
Using a Site Log If you do not receive everything you ordered, contact a Cisco customer service representative for assistance. Using a Site Log It is good practice to use a site log to record all actions taken relevant to router operation and maintenance. Keep the site log near the router for ready access by the site manager or other personnel.

CHAPTER 3 Installing a Cisco 12008 This chapter presents the procedures for installing and starting the Cisco 12008.
Installation Considerations Installation Considerations The Cisco 12008 offers the following mounting options: • • • • A 2-post, telco-style rack A 4-post, full-height equipment rack Shelf-top mounting Freestanding system The installation procedures presented in this chapter pertain only to the first two of these mounting options. Before attempting to install your Cisco 12008, you should determine the mounting option that you intend to use.
Installing the Mounting Brackets You must allow at least 24 inches (61 cm) of clearance in front of the router enclosure for installing or replacing line cards, fan trays, and power supplies, and for attaching network interface cables or equipment. You cannot use an AC-input power supply and a DC-input power supply in the same router. All power supplies installed in a router must be of the same type.
Installing the Mounting Brackets You can install a single Cisco 12008 at any height in the rack, or you can “stack” as many as three routers in the rack to make maximum use of available rack space. Each installed router requires 25 inches of rack space (63.5 cm). The height of each router is 24.85 inches (63.1 cm), leaving a minimum of tolerance between each rack-mounted router.

Removing Components from the Router Removing Components from the Router For the procedures in this section, it is assumed that you have unpacked the router, as instructed in the document Cisco 12008 Gigabit Switch Router System Packing and Unpacking Instructions posted on the outside of the shipping container.
Removing Components from the Router As you remove the cards from the upper card cage, place them on antistatic mats for ESD protection until they are reinstalled in the router. Caution Note Each line card has a vertical cable-management bracket affixed to it that enables you to neatly “dress” the network interface cables attached to line card ports. Leave this bracket in place when removing the line cards from the router. The RP and the CSC do not require vertical cable-management brackets.
Removing Components from the Router Go back to Step 3 and repeat the procedure as many times as necessary to completely depopulate the upper card cage. Stack the removed cards on the antistatic mat in their order of removal, thus leaving them properly ordered for later reinstallation.
Removing Components from the Router Removing a Power Supply from the Router The router is shipped with all the circuit boards and the AC-input or the DC-input power supply(ies) already installed, as ordered, but without any cables connected. To remove a power supply from the router, perform the following steps: Step 1 Set the rotary power switch on each power supply, as follows: • • For an AC-input power supply—Set the switch to the Standby position.
Removing Components from the Router Go back to Step 1 and repeat the procedure to remove the second power supply, if one is present.
Rack-Mounting the Cisco 12008 If you intend to use your router with a single power supply of either type, the power supply blank must remain in place at all times for EMI compliance and to ensure that cooling air flows properly through the router. Rack-Mounting the Cisco 12008 This section presents the procedures for mounting the Cisco 12008 in a rack.
Rack-Mounting the Cisco 12008 Lifting Handles for the Cisco 12008 H11769 Figure 3-4 Note If you did not install the optional mounting brackets in the rack, two people must support the weight of the router while holding it in position for installation; a third person must then secure the router in the rack using the screws provided in the accessories box.
Rack-Mounting the Cisco 12008 Installing the Router in the Rack H11767 Figure 3-5 Step 5 Remove the two lifting handles from the side panels of the router before attempting to slide the router into the rack. Step 6 Slide the router into the rack until the rack-mounting flanges on each side of the router rest against the rack-mounting posts.
Reinstalling Components in the Router In standard EIA and telco-style racks, the holes in each mounting post should align with the holes in each rack-mounting flange on the router, as follows: • The pattern of holes at the top of the left and the right router mounting flanges should match at least two holes in each of the two mounting posts. • The pattern of holes at the bottom of the left and the right router mounting flanges should match at least two holes in each of the two mounting posts.
Reinstalling Components in the Router Step 4 Grasp the front edge of the metal card carrier with one hand and place your other hand under the carrier to support the card’s weight and guide it into the card cage slot. Note Alignment grooves at the top and bottom of each slot in the upper card cage help you to align the cards properly for insertion. Make sure you properly align the card carrier with these alignment grooves to facilitate card insertion.
Reinstalling Components in the Router To reinstall a power supply that was removed prior to rack mounting the router, perform the following steps: Step 1 Verify that the rotary power switch on the power supply to be reinstalled is set, as follows: • • For an AC-input power supply—Set to the Standby position. For a DC-input power supply—Set to the OFF position.
Connecting the Line Card Cables This action engages the blind mating connector at the rear of the power supply with its companion backplane connector. To prevent damage to the backplane, do not use excessive speed or force when sliding the power supply into the bay. Caution Step 6 Using a flat-blade screwdriver, turn the captive installation screw on the power supply faceplate clockwise until it is tight, thus securing the power supply in the bay.
Connecting the Line Card Cables To install the network interface cables in the cable-management system and connect the cables to the line cards, perform the following steps: Step 1 Attach an antistatic ESD wrist strap to your wrist; ensure that it makes good contact with your skin. Step 2 Insert the equipment end of the wrist strap (the banana jack) into the ESD connection socket near the lower left corner of the upper card cage.

Connecting Route Processor Cables When you have completed installing the network interface cables on the left-most line card, proceed to the next card in turn in the upper card cage. Repeat this procedure until you have installed all of the network interface cables on all of the line cards present in the upper card cage. Connecting Route Processor Cables The console and auxiliary ports for the Cisco 12008 are located on the RP. The GRP has an optional Ethernet port and the PRP has two Ethernet ports.

Connecting Route Processor Cables Note You must provide the EIA/TIA-232 cables to connect the terminal to the GRP console port or other devices to the auxiliary port. Cisco Systems does not provide console and auxiliary port cables; cables are available from other vendors. For compliance with GR1089 (intra-building surge), you must use shielded cables on the GRP console and auxiliary ports.
Connecting Route Processor Cables GRP Auxiliary Port Signals The auxiliary port on the GRP is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to the Cisco 12008. The port is located above the console port on the GRP faceplate. The auxiliary port supports hardware flow control and modem control. An example of a modem connection is shown in Figure 3-7. Table 3-2 lists the signals used on the auxiliary port.
Connecting Route Processor Cables Note At the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides maximum usable bandwidth that is less than 100 Mbps; a maximum usable bandwidth of approximately 20 Mbps should be expected from either the RJ-45 or MII connections. Transmission speed is determined by the network to which the Ethernet interface is connected and is not user-configurable.
Connecting Route Processor Cables Depending on the type of media you use between the MII receptacle and your switch or hub, the network side of your 100-Mbps transceiver should be appropriately equipped with ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 3-9 shows the pin orientation of the female MII receptacle on the Ethernet port.

Connecting Source Power to the Power Supplies Step 6 Place the grounding lug against the grounding receptacle on the side panel of the router. Step 7 Insert two screws through the holes in the grounding lug and the grounding receptacle. Ensure that the grounding lug will not interfere with other router hardware or rack equipment. Step 8 Install the locking washers and nuts; tighten them to secure the grounding lug to the grounding receptacle. Step 9 Reinstall the rear access cover on the router.
Connecting Source Power to the Power Supplies Note You should not install two power supplies of either type unless you intend to use both units. In other words, you should not install two power supplies and power the router with only one of the units. Powering the router with a single power supply while using the other bay to “store” an inert unit may disrupt the normal flow of cooling air through the power supply bays.
Connecting Source Power to the Power Supplies To connect source power to an AC-input power supply, perform the following steps: Step 1 Verify that the rotary power switch on the power supply is in the Standby (OFF) position. Note A power supply bay not occupied by a power supply must have a power supply blank installed for EMI compliance and to ensure proper airflow through the router.
Connecting Source Power to the Power Supplies Step 5 Connect the other end of the AC power cord to the source AC outlet for your site (see Figure 3-19). Step 6 Go back to Step 1 and repeat the procedure to connect source AC power to the second (redundant) AC-input power supply, if one is present. Caution At this time, do not turn the rotary power switch to the ON (|) position on either a single or a redundant AC-input power supply.

Before applying power to your Cisco 12008, go to the section entitled “Starting the Cisco 12008.
Connecting Source Power to the Power Supplies Connecting Source Power to a DC-Input Power Supply In the following procedure, you are assumed to have a DC-input power supply already installed in your router; you need to connect it to a DC power source. If a DC-input power supply is not already installed, perform the procedures in the earlier section entitled “Reinstalling the Power Supplies in the Router” before attempting to connect source DC power to the unit.
Connecting Source Power to the Power Supplies Also, before attempting to connect source power to a DC-input power supply, review the content of the section in Chapter 2 entitled “DC-Powered Systems,” which deals with the following topics: • • • Specifications for source DC input power (see Table 1-10 in Chapter 1) Specifications of the source DC power cable and lug (see Table 2-2 in Chapter 2) Dimensions of the lugs used with the source DC power cables (see Figure 2-6 in Chapter 2) To connect source pow
Connecting Source Power to the Power Supplies Note The color coding scheme used for the source DC power cables for the DC-input power supply depends on the scheme used for the site DC power source. Typically, green or green/yellow is used for earth ground, red is used for positive (+), and black is used for negative (–). Make certain that you properly map the color coding scheme used at the site for the DC power source to the proper terminals on the DC-input power supply faceplate.

Starting the Cisco 12008 Step 7 If you intend to attach an external alarm monitoring facility to the circuit breaker alarm terminal block on the power supply, do so at this time. For an illustration of how the leads from the alarm monitoring facility are connected to the alarm terminal block, refer to Figure 7-9 in the section entitled “Adding a DC-Input Power Supply” in Chapter 7.
Starting the Cisco 12008 To start up your Cisco 12008, perform the following steps: Step 1 Step 2 Verify that the following conditions are satisfied: • • • Each line card is fully seated and its captive installation screws are tightened. • A vertical cable-management bracket is attached to each installed line card and the bracket’s captive installation screws are tightened.
Starting the Cisco 12008 • Step 3 For the DC-input power supply(ies), the green INPUT OK LED should go on. Listen for the fans in the card cage fan tray and the power supply fan tray to power up. You should hear the fans come up to normal rotational speed in about 2 seconds. In a noisy environment, you can check fan operation by placing your hand in front of the air filter assembly and the power supply fan tray to determine if air is being drawn into the interior of the router.
CHAPTER 4 Observing System Startup and Performing a Basic Configuration This chapter describes the initial system startup process and provides procedures for performing a basic configuration for your Cisco 12008.
Sources of Cisco IOS Software This chapter will help you to • • Configure your router so that it can access the network Enable other hosts in the network to remotely access your system by means of a Telnet connection Detailed configuration procedures for all of the line cards and network interfaces that you can install in your Cisco 12008 are beyond the scope of this document.
Checking Conditions Prior to System Startup Checking Conditions Prior to System Startup Before attempting to start up your system, verify that the following conditions exist: • All line cards in the upper card cage are fully inserted into their slots; all captive installation screws on the line cards are tightened. • • • All clock and scheduler cards (CSCs) in the upper card cage are fully inserted. • • • Source power for the power supply(ies) is properly connected.
Starting the System and Observing Initial Conditions Starting the System and Observing Initial Conditions This section describes the initial system startup processes and procedures. To start up your Cisco 12008, perform the following steps: Step 1 Apply power to each installed power supply by turning its rotary power switch fully clockwise to the ON (|) position. As power is applied to the AC-input power supply(ies), both the green AC INPUT OK LED and the red OUTPUT FAIL LEDs go on momentarily.

For example, microcode version 1.17 would display as 0117.
Starting the System and Observing Initial Conditions Step 4 During the line card boot process, which occurs immediately following that of the RP, observe the alphanumeric LEDs on each line card. The alphanumeric LEDs on a line card are also located at the bottom of the line card faceplate (see Figure 4-2).

For example, microcode version 1.17 would display as 0117.1 This display might not be visible, since it occurs briefly. MBus controller LMEM TEST Low memory on the line card is being tested.
Starting the System and Observing Initial Conditions Note If a Flash memory card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0 and the software configuration register is set to 0x0102 (the factory default setting), the system automatically boots using this image. The system then enters the setup facility, prompting you to perform a basic system configuration by means of an interactive script (see Step 9).
Starting the System and Observing Initial Conditions Step 6 To locate a desired Cisco IOS software image for manually booting the router from the ROM monitor prompt (rommon>), first determine the contents of the onboard Flash memory SIMM (NVRAM) on the RP by issuing the directory command: rommon 1> dir bootflash: File size 3277967 bytes (0x32048f) rommon 2> Checksum 0x6b331e30 File name gsr-p-mz.112-9.GS4 If the onboard Flash memory SIMM contains the desired Cisco IOS boot image, proceed to Step 8.
Starting the System and Observing Initial Conditions This command boots the specified file from the Flash memory card in PCMCIA slot 1. rommon 3> boot tftp:gsr-p-mz.112-9.GS4 This command boots the specified file from the host TFTP boot server in the network.
Configuring the Cisco 12008 The system asks you if you want to continue with the configuration dialog. If you answer yes, the system proceeds with the interactive script for the setup facility. If you answer no, the system exits from the setup facility. In this case, you must issue configuration commands at the console terminal to configure the system and network interface parameters.
Configuring the Cisco 12008 You can perform a basic configuration for your Cisco 12008 using either of the following methods: • Method 1—Using the setup facility or the setup command. At initial startup of a completely unconfigured router, the system automatically defaults to the setup facility, which enables you to begin manually configuring your router. The setup facility presents a structured, interactive script that guides you through the process of manually configuring your router.
Configuring the Cisco 12008 Using the Setup Facility or the Setup Command You must consider the following types of parameters during the initial manual configuration of your router: • • Global (system-wide) parameters Network interface (line card) parameters As noted earlier, you can establish the above parameters using the setup facility (as presented to you automatically at initial system startup), or you can issue the setup command at any time at the privileged EXEC prompt (Router#) to activate the s
Configuring the Cisco 12008 Configuring Global Parameters When you first enter the setup facility or issue the setup command, you are queried by the system to configure global parameters for your router. To boot the system and establish global configuration parameters, perform the following steps: Step 1 Connect a console terminal to the console port on the RP. Step 2 Boot the system to display the user EXEC prompt (Router>).
Configuring the Cisco 12008 2 four-port OC3 POS controllers (8 POS). 5 OC12 POS controllers (5 POS). 1 Ethernet/IEEE 802.3 interface(s) 13 Packet over Sonet network interface(s) 507K bytes of non-volatile configuration memory. 20480K bytes of Flash PCMCIA card at slot 0 (Sector size 128K). 8192K bytes of Flash internal SIMM (Sector size 256K). Notice: NVRAM invalid, possibly due to write erase.
Configuring the Cisco 12008 Pressing Return in either case accepts the default response [yes]. The following sample display results from a yes response to the current interface summary query that is entered while you are using the setup facility.
Configuring the Cisco 12008 A typical minimum configuration procedure using IP follows and continues through Step 8: Configuring global parameters: Enter host name [Router]: Router Step 5 Enter the enable secret password when prompted to do so: The enable secret is a one-way cryptographic secret used instead of the enable password when it exists. Enter enable secret [
Configuring the Cisco 12008 In either case, you cannot use a number as the first character. Spaces, however, are valid password characters. For example, “two words” is a valid password. Leading spaces are ignored, but trailing spaces are recognized. Step 7 Enter the virtual terminal password when prompted to do so: Enter virtual terminal password: bambam For future use, make a note of this password. Step 8 In most cases, you will use IP routing as the network layer protocol.
Configuring the Cisco 12008 Note SNMP is the most widely supported standard for managing networks. SNMP provides a means to access and set configuration and run-time parameters and to monitor and control network elements for routers and communication servers. For more information about SNMP, refer to the appropriate software configuration publications listed in the section entitled “If You Need More Configuration Information.
Configuring the Cisco 12008 The display indicates the order in which the parameters and their defaults appear on your console terminal.
Configuring the Cisco 12008 Note The sample configuration dialog in this section continues the script displayed when you used the setup facility or the setup command in establishing the system’s global parameters (see the section entitled “Configuring Global Parameters”). The output shown in this section is only an example; your configuration dialog might be different, depending on how you configure your router.
Configuring the Cisco 12008 Also, consider Step 3 below, which shows this same Quad OC-3c POS line card interface being configured for IP unnumbered; perform whichever step is appropriate to your configuration requirements. Configuring interface POS4/0: Is this interface in use?: yes Configure IP on this interface?: yes Configure IP unnumbered on this interface?: no IP address for this interface: 2.1.1.1 Number of bits in subnet field: 0 Class A network is 2.0.0.0, 0 subnet bits; mask is 255.0.0.
Configuring the Cisco 12008 Repeat Step 2 or Step 3, as required, to individually configure each port on every Quad OC-3c POS line card installed in your system. If you have an ATM line card installed in your router, proceed with Step 4; otherwise, skip to Step 5. Step 4 Configure the ATM line card interface(s). Asynchronous Transfer Mode (ATM) interfaces enable connections to external OC-12/STM-4 networks. In the following example, an ATM line card is being configured to use IP.
Configuring the Cisco 12008 Step 5 When you have completed entering the configuration information for all of the installed line cards, the following configuration query is displayed: Use this configuration? [yes/no]: At this point, you should visually verify all of the configuration parameters displayed on your console terminal.
Configuring the Cisco 12008 Checking the Software Version Number and the Installed Interfaces To determine the current version of the Cisco IOS software running on your router, issue the show version command at the user EXEC prompt (Router>). This command causes the Cisco IOS version number to be displayed, as well as other information, including the hardware installed in the system, the names and sources of system image files, and the contents of the software configuration register.
Configuring the Cisco 12008 20480K bytes of Flash PCMCIA card at slot 0 (Sector size 128K). 8192K bytes of Flash internal SIMM (Sector size 256K). Configuration register is 0x0102 Using the Global Configuration Mode If you prefer not to use the interactive script of the setup facility, you can manually configure your router using the global configuration mode. The global configuration mode enables you to enter configuration commands on a line-by-line basis from the console terminal.
Configuring the Cisco 12008 At the global configuration mode prompt, enter the interface type slot/port command to enter the interface configuration mode: Router(config)# interface type slot/port Router(config-if)# This command accepts either POS or ATM as the type argument. In either the global configuration mode or the interface configuration mode, you can change the router’s configuration parameters. To exit either mode, type Ctrl-Z.

Performing Other Configuration Tasks Performing Other Configuration Tasks This section presents procedures for performing the following additional configuration tasks: • • • Configuring the Software Configuration Register Recovering a Lost Password Using Flash Memory Cards in the RP Configuring the Software Configuration Register The software configuration register is a 16-bit register in NVRAM that you use to define specific system parameters.
Performing Other Configuration Tasks • Force an automatic boot using a boot image. When you first power on the router, a boot image called the RP ROM monitor is executed, resulting in the display of the ROM monitor prompt (rommon>). At this prompt, you have access to a limited set of commands that enable you to set values in the software configuration register and to perform a number of other tasks. The RP ROM monitor is loaded into the RP Flash ROM during board manufacture.
Performing Other Configuration Tasks Table 4-3 Definition of Bits in the Software Configuration Register (Continued) Bit Number Hexadecimal Value Meaning/Function 11 and 12 0x0800 to 0x1000 Defines the console baud rate (the default setting is 9600 baud). 13 0x2000 Boots the default Flash memory software if the network boot fails. 14 0x4000 IP broadcasts do not have network numbers. 15 0x8000 Enables diagnostic messages and ignores the contents of NVRAM. 1.
Performing Other Configuration Tasks Boot Field Settings and the Use of the Boot Command The four low-order bits of the software configuration register (bits 3, 2, 1, and 0) form a boot field that defines the source of a Cisco IOS software image for booting the router. You can set or change the contents of the boot field by issuing the config-register command at the global configuration mode prompt [Router(config)#].
Performing Other Configuration Tasks • When the boot field is set to 1, the system automatically boots using the first image found in the onboard Flash SIMM on the RP. If you set the boot field to any bit pattern other than 0 or 1, the router uses the software configuration register settings to compute a filename from which to boot a default system image stored on a network TFTP server.
Performing Other Configuration Tasks Note If a bootable Cisco IOS software image exists in a Flash memory card inserted in PCMCIA slot 0 or slot 1, the software configuration register boot field setting is overridden and the system boots from the Cisco IOS software image in the Flash memory card, rather than from a network TFTP image (that is, from a computed filename in the range from cisco2-grp through cisco17-grp).
Performing Other Configuration Tasks The new contents of the software configuration register are saved to NVRAM. However, these new settings do not take effect until you reload the system or reboot the router. Step 5 To display the software configuration register setting that is currently in effect as a result of Step 3 (and which will be used at the next reboot of the router), issue the show version command at the privileged EXEC mode prompt: Router#sh ver . . .
Performing Other Configuration Tasks If you set the boot field value to 0x2 through 0xF and a valid boot system command is stored in the configuration file, the system boots the Cisco IOS software image as directed by that value. If no boot system command is present in the configuration file, the system computes a default boot filename for booting from a network TFTP server.

Performing Other Configuration Tasks Bit 10 of the software configuration register controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to use all zeros in the host portion of the IP broadcast address; clearing bit 10 (the factory default) causes the processor to use all ones. Bit 10 interacts with bit 14, which controls the network and subnet portions of the IP broadcast address. Table 4-6 shows the combined effect of bits 10 and 14.
Performing Other Configuration Tasks bit 13 causes the system to continue attempting to load a boot file from the network TFTP server indefinitely. By default, bit 13 in the software configuration register is set to 0 at the factory prior to router shipment. Table 4-3 summarizes the functions of all of the bits in the software configuration register. Recovering a Lost Password This section tells you how to recover a lost password.
Performing Other Configuration Tasks Step 3 Enter the show version command at the privileged EXEC mode prompt to display the current software configuration register setting: Router#show version . . . Make a note of this current configuration setting, as displayed in the last line of the show version command output. You may need this value for later use (in Step 13).

Performing Other Configuration Tasks Formatting a Flash Memory Card The Flash memory card that shipped with your router contains the default Cisco IOS image for booting your router. In some cases, you might need to insert a new Flash memory card and copy images or backup configuration files to the card. However, before using a new Flash memory card, you must format it. Note For the following procedure, it is assumed that you have already booted your router and that it is fully operational.
Performing Other Configuration Tasks The new Flash memory card is now ready for use. Specifying a Cisco IOS Image for Booting the System Use the procedure in this section to identify a particular Cisco IOS software image (named new.image) that is to be made bootable from a Flash memory card.
Performing Other Configuration Tasks Console Commands Associated with Flash Memory Use This section outlines the console commands for using the onboard Flash memory SIMM on the RP and the PCMCIA Flash memory cards.

Performing Other Configuration Tasks Note During the squeeze operation, the system maintains a log identifying which of the squeeze functions has been accomplished so that the system can return to the proper place and continue the operation in the event of a power failure. The character “Z” indicates that the log has been erased following the successful squeeze operation.
Performing Other Configuration Tasks Copying Files to a Flash Memory Medium It is a good idea to copy a new Cisco IOS software image to a Flash memory medium (1) when a new image becomes available or (2) when you want to back up the image. The information in this section enables you to copy any type of file to the Flash memory SIMM on the RP or to a PCMCIA Flash memory card inserted in either slot 0 or slot 1.

CHAPTER 5 Troubleshooting the Installation Your Cisco 12008 was subjected to extensive testing and burn-in before being shipped from the factory. However, if you encounter problems starting up the router, the information in this chapter will help you to isolate the probable cause.
Troubleshooting Overview If you cannot solve a problem, contact a customer service representative for assistance.
Troubleshooting Overview Table 5-1 Status of Alphanumeric Displays and LEDs at System Startup Card LED Function Display Contents/LED Status/Meaning RP LED alphanumeric displays MSTR (top) RP (bottom) The RP is enabled and recognized by the system; a valid Cisco IOS software image is running. Line card LED alphanumeric displays IOS (top) RUN (bottom) The line card is enabled and ready for use. CSC(s) System alarm LEDs CRITICAL: OFF MAJOR: OFF MINOR: OFF No system alarm conditions exist.
Troubleshooting Overview Problem Solving Using a Subsystem Approach The key to solving system problems is to try to isolate the difficulty to a specific subsystem. The first step in solving startup problems, for example, is to compare what the system is doing to what it should be doing. Since a startup problem is usually attributable to a single component, it is more effective to isolate the problem to a specific subsystem, rather than trying to troubleshoot each system component.
Troubleshooting Overview Each fan tray incorporates individual fans that draw +24 VDC from a DC-DC converter on the CSC that operates under control of its onboard MBus module. Both fan trays should begin to operate about two seconds after application of system power.
Troubleshooting Overview • Processor subsystem—The processor subsystem includes the RP and all installed line cards. Each line card has an onboard processor, to which the RP downloads a copy of the Cisco IOS operating image. A line card or RP that is not firmly seated in the backplane might cause the system to hang and crash. Two 4-character alphanumeric displays at the bottom of the RP and each line card provide status and error messages that can be an aid in troubleshooting.
Troubleshooting Overview • The MBus module on the RP monitors the progress of the CSC power-up sequence. When the CSC is powered up, the MBus module on the RP turns on its DC-DC converter to power its own electronics. • The master MBus module on the RP then sends instructions to each line card and each SFC to power up; the MBus module on each card then turns on its own onboard DC-DC converter. — The MBus module on each line card monitors its progress during the power-up sequence.
Troubleshooting Overview If this LED does not go on, or if it goes off while system power is still applied, there could be a problem with either the source power itself or the DC output voltages being delivered to the backplane (+5 VDC and –48 VDC). There could also just be a problem with the MBus controller inside the power supply.
Troubleshooting Overview — If the AC INPUT OK LED (on the AC-input power supply) or the INPUT OK LED (on the DC-input power supply) goes on, and the system starts up as expected but then displays the following message and shuts down after 2 minutes, there may be a problem with one of the fan trays. %ENVM-2-FAN: Fan has failed, shutdown in 2 minutes In this case, proceed to the section entitled “Troubleshooting the Cooling Subsystem.
Troubleshooting the Power Subsystem Troubleshooting the Power Subsystem The power subsystem in the Cisco 12008 consists of the following: • • • • AC-input or DC-input power supply(ies) MBus modules on the individual cards DC-DC converters on the individual cards Power distribution system in the Cisco 12008 (see Figure 1-23) Each power supply provides +5.2 VDC and –48 VDC output voltages to the backplane. The +5.2 VDC output powers the MBus modules on each card in the system.
Troubleshooting the Power Subsystem — If the answer is no, but the fan trays are operating and the alphanumeric displays on the RP and line cards are functional, the likely suspect is a faulty power supply LED. The MBus modules driving the alphanumeric displays are powered by +5.2 VDC from the power supply. The fan trays are powered by +24 VDC from the DC-DC converter on the CSC; hence, if the RP and the fan trays are operating normally, all internal DC voltages are within tolerance.
Troubleshooting the Processor Subsystem • In systems powered by source DC, check the cable connections to the terminal studs on the DC-input power supply faceplate to ensure that the correct polarity (+ and –) has been observed in making the connections.
Troubleshooting the Processor Subsystem The MBus module processor begins to operate as soon as power is applied to the system. The MBus processor determines what type of card it is mounted on and whether it should turn on the card’s DC-DC converter. The master MBus module on the RP turns on card power after a brief delay; the MBus modules on the line cards delay turning on power until they receive a command to do so from the RP master MBus module.
Troubleshooting the Processor Subsystem Some messages appear briefly (millisecond duration), and others last several seconds. If one of the messages appears frozen, the boot process could be hung. Note the message being displayed on a piece of paper. Turn off the system power supply power switches, then turn them back on to reset the system and start the boot process anew. If the system hangs again, the RP could be faulty and in need of replacement.
Troubleshooting the Processor Subsystem • Is a critical, major, or minor alarm LED on the CSC(s) on? — If any one of the three system alarm LEDs is on, a fault has been detected in the system. Check the console for messages indicating the source of the problem. — A false error indication may be originating from the RP. Reseat or replace the RP. Caution The RP reset switch resets the RP and the entire system.
Troubleshooting the Processor Subsystem process continues on the line card. Table 5-3 lists the messages that appear in the line card alphanumeric display. Some messages are displayed for only a few milliseconds, and others are displayed for several seconds.
Troubleshooting the Cooling Subsystem CSC Alarm Functions The CSC incorporates the following system and component alarm functions: • Primary system alarm functions—The system’s primary alarm LEDs are incorporated into the CSC faceplate (see Figure 3-16). From top to bottom, these LEDs correspond to three levels of severity for system alarm conditions: critical, major, and minor.
Troubleshooting the Cooling Subsystem • Power supply fan tray—This fan tray is mounted in the lower right corner of the router enclosure. Each fan tray operates from +24 VDC that is distributed to it through the backplane from a DC-DC converter on the CSC. A recessed, blind-mating connector in the back of each fan tray provides connectivity to the backplane. Both fan trays are essential; they provide sufficient cooling air for the router’s components and electronic circuitry.
Troubleshooting the Cooling Subsystem 5 Tighten the fan tray captive installation screws. 6 Reinstall the air filter assembly. If the left fan tray LED remains on after reseating the card cage fan tray, the unit is faulty and should be replaced. If the right fan tray LED on the CSC faceplate is on (amber), reseat the power supply fan tray in the backplane, as follows: 1 Loosen the captive installation screw on the fan tray faceplate.
Additional Troubleshooting Reference Information +3.3 VDC and +5 VDC from the DC-DC converter, the +5.2 VDC for the MBus module, and the operating voltage for the fan trays. Each command also displays the temperature measurements made by two sensors on each card (one for inlet air temperature and one for the card’s hot-spot temperature), as well as a temperature measurement made by a sensor in the power supply(ies).
CHAPTER 6 Running Diagnostics on the Cisco 12008 Field diagnostics are available for the Cisco 12008 to help you isolate faulty hardware to the level of a field-replaceable unit (FRU) without disrupting the operation of the system. After you identify the faulty unit, you can replace it with a spare unit. Field diagnostics are not designed to identify specific components within the router. They simply determine whether a particular card is operational or defective.
Using the diag Command Note When using Cisco IOS Release 12.0(21)S or 12.0(21)ST, or a later release of 12.0S or 12.0ST, the default download method changes from the mbus to the switch fabric. It takes about 1-minute to obtain test results from the switch fabric compared to 15-minutes to obtain test results from the mbus. While diagnostics are running, the line card being tested is controlled by the diagnostic software. Diagnostics take the line card under test offline.
Diagnostic Testing Sequence where: slot Specifies which card cage slot to test. The diagnostic software determines the type of card in the slot and downloads the appropriate tests. halt (Optional) Stops the active diagnostic test. previous (Optional) Allows you to examine the last test results on the card, stored in EEPROM, specified by the slot parameter. mbus1 (Optional) Forces the route processor to load diags from the mbus.
Loading and Running Diagnostics 2 Downloads a diagnostic image from the RPs running IOS software to the line card before testing. The Cisco IOS software image is removed from the line card DRAM and is replaced with the diagnostic software image for the duration of the tests. 3 Sends and receives messages across the MBus to and from the card being tested. During the testing process, messages are passed from the line card under test to the RP.
Loading and Running Diagnostics Step 2 Enter the password assigned to the system. The prompt changes to the privileged EXEC prompt: Router# Step 3 Determine the slot number of the card on which you want to run diagnostics. Note Although you can run diagnostics concurrently on up to three line cards, the recommended number is only one at a time. The cards will be taken offline and cannot pass traffic. Step 4 Enter the diag command: Router# diag slot The diagnostic tests are downloaded and run.
Loading and Running Diagnostics Without verbose Option To see how the verbose option changes the messages from the diagnostics to the console, refer to the following examples. In the first example, diagnostics are run on a line card installed in slot 2 in the card cage. The diagnostics are run without the verbose option set (minimum messaging). The console displays a message sequence similar to the following, showing the progress of the diagnostic testing.

Loading and Running Diagnostics Note The DRAM is the only field-replaceable component on a line card; therefore, if a diagnostic test fails, you must replace the line card, which is the field-replaceable unit (FRU).
CHAPTER 7 Maintaining the Cisco 12008 After your Cisco 12008 has been operational for a period of time, you might need to perform specific maintenance tasks, replace certain field replaceable units (FRUs), upgrade memory components, or perform other tasks to ensure that the router continues to operate properly and reliably.
Cleaning the Air Filter Cleaning the Air Filter The Cisco 12008 has a removable air filter assembly that forms part of the outer enclosure of the lower card cage (see Figure 7-1). This card cage accommodates a fan tray containing six fans that provide cooling air for all of the router’s internal electronic circuitry, including all of the cards installed in the upper card cage slots and the optional set of three SFCs that you can install in the lower card cage slots.
Cleaning the Air Filter Step 2 Inspect the condition of the air filter and decide if it should be removed and cleaned. Step 3 To remove the filter, slide it off the two panel fasteners (see Figure 7-1). Exercise care to prevent damage to the honeycomb screen in the EMI frame. Damage to the honeycomb screen might reduce its EMI suppression characteristics and restrict the flow of cooling air through the router. Caution Step 4 Vacuum both sides of the filter thoroughly.

Installing and Removing a Blank Filler Panel Installing and Removing a Blank Filler Panel The Cisco 12008 must be fully enclosed to ensure that cooling air is circulated properly throughout the interior of the router. Fully enclosing the router prevents overheating of electronic components in the upper and lower card cages and suppresses EMI radiation. To cover any vacant slot in the upper card cage of the Cisco 12008, you must install a blank filler panel (see Figure 7-2).

Adding, Removing, or Replacing an AC-Input Power Supply Adding, Removing, or Replacing an AC-Input Power Supply The Cisco 12008 can operate with either one or two AC-input power supplies. Although the router supports an online insertion and removal (OIR) capability for field replaceable units (FRUs), you must observe the following rules regarding the AC-input power supplies: • If your Cisco 12008 is configured with a single AC-input power supply, you must power down the system before replacing the unit.
Adding, Removing, or Replacing an AC-Input Power Supply Note It is recommended that you connect each AC-input power supply to an independent source of power with a 20A service. It is also recommended that you use an uninterruptable power source (UPS) for your site to protect against a site power failure.

In this case, you must power down the router before removing the power supply.
Adding, Removing, or Replacing an AC-Input Power Supply It is also assumed that the power supply to be removed is installed in the lower power supply bay, which, by convention, is the normal configuration for a single power supply. Lastly, in such a single power supply configuration, it is assumed that the upper power supply bay has been previously covered by a blank filler panel to ensure EMI compliance and the proper flow of cooling air through the router.
Adding, Removing, or Replacing an AC-Input Power Supply Step 8 Place your free hand beneath the power supply to support its weight and withdraw the unit completely from the bay. Step 9 Set the power supply aside, pending further disposition. If you intend to return the removed power supply to the factory for repair or replacement, repackage the unit properly for return shipment using the original packing materials, if available.
Adding, Removing, or Replacing an AC-Input Power Supply Step 5 Release the bail latch that secures the source AC power cord to the AC receptacle on the power supply faceplate. Step 6 Remove the power cord from the AC receptacle. Step 7 Grasp the power supply carrying handle with one hand and pull the unit halfway out of the bay to disengage the blind-mating connector at the back of the power supply from the backplane. Warning The AC-input power supply weighs 17 lb (7.73 kg).
Adding, Removing, or Replacing an AC-Input Power Supply Note All the necessary electrical connections between the power supply and the backplane are accomplished automatically by means of the blind-mating connectors. Step 14 Using a 1/4-inch flat-blade screwdriver, tighten the captive installation screw on the power supply faceplate. Step 15 Connect the source AC power cord to the AC receptacle on the power supply faceplate.
Adding, Removing, or Replacing an AC-Input Power Supply • The source end of the AC power cable is properly connected to the main source AC circuit breaker. • The main source AC circuit breaker servicing the AC-input power supply is ON. • The source AC voltage is within the range specified on the power supply faceplate. • When two AC-input power supplies are installed, each power cord is connected to a separate AC power source.
Adding, Removing, or Replacing a DC-Input Power Supply • If the OUTPUT FAIL LED behaves as expected, proceed with normal system operations. • If the OUTPUT FAIL LED remains on when the new power supply is installed and powered up, the power supply may be faulty, or an adverse environmental condition may exist in the router, such as an overvoltage or overtemperature condition that causes the power supply to shut down.
Adding, Removing, or Replacing a DC-Input Power Supply To add, remove, or replace a DC-input power supply, you need the following tools: • A 1/4-inch flat-blade screwdriver (to loosen/tighten the captive installation screw on the power supply faceplate). • A 10 mm, hollow-shaft nutdriver (to secure the source DC power cables to the terminals on the power supply with the lock washers and nuts). A 1/4-inch socket wrench with a 10 mm deep-well socket will also suffice for this purpose.
Adding, Removing, or Replacing a DC-Input Power Supply To install a second (redundant) DC-input power supply, you must first satisfy the following requirements: • • Ensure that a dedicated 40A service is available for the second power supply. • Ensure that the lugs on the source DC power cables (see Figure 7-5) have dual-holes, centered 0.625 inch apart, and that they will fit over the 0.25-inch M6 (metric) threaded terminals on the DC power supply faceplate (see Figure 7-6).

Adding, Removing, or Replacing a DC-Input Power Supply To add a second (redundant) DC-input power supply to the router, perform the following steps: Step 1 Locate the source DC circuit breaker that will service the DC-input power supply; ensure that this circuit breaker is set to the OFF position. For added safety, tape the circuit breaker handle in the OFF position.
Adding, Removing, or Replacing a DC-Input Power Supply Note The carrying handle on the DC-input power supply is designed to be grasped with your left hand, rather than your right hand. Using your left hand eliminates the potential for catching your fingers in the limited space between the plastic safety shield (see Figure 7-7) and the carrying handle. Warning The DC-input power supply weighs 14 lb (6.36 kg). For safety, use both hands to install the unit in the power supply bay.
Adding, Removing, or Replacing a DC-Input Power Supply (b) Grasp the safety shield and move it to the right and obliquely upward, positioning the shield so that it can be freed from the three standoffs on the power supply faceplate. (c) Remove the shield from the standoffs and set it aside temporarily.
Adding, Removing, or Replacing a DC-Input Power Supply Step 10 As an added safety precaution, it is recommended that you add a length of shrink tubing to the crimp area on each power cable lug (see Figure 7-5) before connecting the leads to the power supply. The shrink tubing acts as an insulator to prevent the crimp area on the source DC power cable lugs from coming in contact with the faceplate of the DC-input power supply.
Adding, Removing, or Replacing a DC-Input Power Supply Note The circuit breaker alarm terminal block enables you to attach an external monitoring facility to the power supply to detect when the power supply circuit breaker trips during an electrical event, such as an overvoltage condition in the power supply. The functions and uses of the circuit breaker alarm terminal block are described in detail in the subsection entitled “Circuit Breaker Alarm Terminal Block” in Chapter 1.

Adding, Removing, or Replacing a DC-Input Power Supply Step 17 Set the circuit breaker to the ON position. Step 18 Set the rotary power switch on the new DC-input power supply to the ON (|) position. To verify that the new DC-input power supply is operating properly, proceed to the section below entitled “Verifying the Installation of a DC-Input Power Supply.
Adding, Removing, or Replacing a DC-Input Power Supply To remove the plastic safety shield (see Figure 7-7), take the following actions: (a) Loosen the knurled thumb wheel on the bottom left standoff that secures the safety shield to the power supply faceplate. (b) Grasp the safety shield and move it to the right and obliquely upward, positioning the shield so that it can be freed from the three standoffs on the power supply faceplate.
Adding, Removing, or Replacing a DC-Input Power Supply Step 8 Using a 10 mm nutdriver (or a 1/4-inch socket wrench with a 10 mm deep-well socket) loosen the nuts securing the negative (–) power cable to the bottom terminals on the power supply faceplate; remove the nuts and locking washers from the terminals and set this hardware aside temporarily.
Adding, Removing, or Replacing a DC-Input Power Supply Replacing a DC-Input Power Supply In the following procedure, it is assumed that you will be replacing an existing power supply in a router containing redundant DC-input power supplies. In this configuration, the router’s online insertion and removal (OIR) capability enables you to replace a given power supply without removing power from the router.
Adding, Removing, or Replacing a DC-Input Power Supply Warning To be completely sure that power has been removed from the source DC circuit presently servicing the power supply that you intend to remove, use a voltmeter to measure the voltage across the negative (–) and positive (+) source DC leads. Set the voltmeter to a range that makes it capable of measuring up to 75 VDC. The measurement across the positive and negative leads should be zero (0) volts.
Adding, Removing, or Replacing a DC-Input Power Supply Step 11 If an external alarm monitoring facility is attached to the circuit breaker alarm terminal block on the power supply faceplate (see Figure 7-9), make a note of how the leads are connected. Doing so enables you to properly identify each lead for later reconnection. Step 12 Disconnect the leads from the circuit breaker alarm terminal block.
Adding, Removing, or Replacing a DC-Input Power Supply Step 20 Gently slide the new power supply into the vacant bay, carefully seating it so that the power supply faceplate is flush against the sheet metal of the power supply bay. This action ensures that the blind-mating connector at the rear of the power supply is firmly seated into the backplane connector. Caution To prevent damage to the blind-mating connectors, do not use excessive speed or force when inserting the new power supply into the bay.
Adding, Removing, or Replacing a DC-Input Power Supply Step 24 Step 25 Before connecting each cable to the appropriate terminals on the power supply faceplate, remove the tape (that you applied in Step 10 above) from the lug. Strictly observe the following order in reconnecting the leads to the power supply terminals: (a) Ground (b) + (positive) (c) – (negative) Secure each cable to the terminals using the previously removed lock washers and nuts.
Adding, Removing, or Replacing a DC-Input Power Supply Verifying the Installation of a DC-Input Power Supply To verify the operation of a newly-installed DC-input power supply, first apply power to the unit and observe the status of the LEDs on the power supply faceplate.
Removing and Replacing the Fan Trays • • Step 4 If the INPUT OK LED goes on, proceed to Step 4. If the INPUT OK LED does not go on after you apply power to the unit and verify the conditions outlined in Step 1, contact your local Cisco service representative for assistance. Observe the behavior of the red OUTPUT FAIL LED on the power supply faceplate after applying power to the unit. This LED should flash on momentarily, then go off and remain so.
Removing and Replacing the Fan Trays The Cisco 12008 supports online insertion and removal of field-replaceable units (FRUs); thus, you can remove and replace a fan tray while the rest of the system remains powered up and fully operational. Note If you replace a defective fan tray while the router is running, you must do so quickly to minimize the risk of overheating router components.
Removing and Replacing the Fan Trays Caution The card cage fan tray weighs approximately 12 lb (5.45 kg). For safety, use both hands when handling this assembly. If you plan to return the removed fan tray to the factory for repair or replacement, repackage the unit in the original shipping container, if available, and prepare the package for return shipment.

Removing and Replacing the RP Removing and Replacing the RP The following sections present the procedures for removing and replacing the RP. The RP can be installed in any of the upper card cage slots 0 through 3 and 4 through 7. By convention, however, it is normally installed in slot 0 (the left-most slot in the upper card cage). Removing the RP while the system is operating will cause the system to stop forwarding packets and might cause the system to cease network operation.
Removing and Replacing the RP Caution Before replacing the RP with another, back up the running configuration file to a Trivial File Transfer Protocol (TFTP) file server or an installed Flash memory card. Doing so enables you to retrieve the file later for reuse. If you do not back up the configuration file, it will be lost and you will have to manually reenter the configuration information for the router.
Removing and Replacing the RP Step 5 Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws at the top and bottom of the RP faceplate (see Figure 7-15a). Step 6 Place your thumbs on each of the ejector levers and simultaneously pivot them away from the RP faceplate (see Figure 7-15b). This action disengages the RP from the backplane.

Removing and Replacing Line Cards Checking the Installation of the RP To verify that the new (or reinstalled) RP is functioning properly, perform the following steps: Step 1 Verify the following conditions: • • • The RP is fully seated and its two captive installation screws are tightened. The RP interface cables are connected and secure. Any Flash memory cards removed from the old RP are reinstalled in the new RP.
Removing and Replacing Switch Cards When you install a new CSC or SFC, the router’s OIR capability enables the new card to be recognized, initialized, and become operational in a transparent manner. For the procedures in this section, it is assumed that you will be removing and replacing a switch card from a fully redundant and operational router. When you replace a failed switch card, only four switch planes remain available to the router.

Removing and Replacing Switch Cards To verify that a new switch card is operating properly, perform the following steps: Step 1 Observe the LEDs on the faceplate of the CSC(s), as follows: • For a new CSC—Observe the two status LEDs for the CSC (refer to Figure 7-20). If the bottom (ENABLED) LED is on (green), the new CSC is operational. If the top (FAIL) LED is on (amber), the new CSC is faulty (see Table 7-2). In this case, proceed to Step 3.
Removing and Replacing Switch Cards Step 2 The secondary indication of SFC status is provided by two LEDs on each SFC (see Figure 7-21). Figure 7-21 Left LED (OK) Status LEDs on an SFC Right LED (FAIL) H11366 Status LEDs Observe each pair of LEDs on each SFC for the following indications: • • Step 3 If the left LED (OK) is on (green), the SFC is operational. If the right LED (FAIL) is on (amber), the SFC is faulty. In this case, proceed with Step 3.
Removing and Replacing the Cable Management System In Step 2 above, since the SFCs are not visible during normal operation, you must remove the air filter assembly from the router to observe the status LEDs on each SFC (see Figure 7-21). These LEDs are arranged side-by-side behind a raised tab near the middle of the card (as you view the SFC from the front of the router).

Upgrading Memory on a Line Card Upgrading Memory on a Line Card This section presents the procedures for upgrading memory on a Cisco 12000 series line card. The Cisco 12000 series line cards used with the Cisco 12008 incorporate the following types of onboard memory: • DRAM—Each Cisco 12000 series line card has two DRAM DIMM sockets (see Figure 7-30). The DRAM is used by the line card’s processor. The default DRAM configuration for the line card’s processor is 32 MB—one 32-MB DIMM in socket P4 DIMM0.

Upgrading Memory on a Line Card Removing a Line Card from the Router This section presents the procedures for removing a line card from the router. The router supports online insertion and removal (OIR) of line cards; thus, you can remove and replace any line card while the system remains powered up and operational. Note When removing or installing a line card, be sure to use the ejector levers to properly unseat and reseat the card in the backplane connector.

Upgrading Memory on a Line Card Step 6 Grasp the line card faceplate with one hand and pull the line card straight out of the slot, keeping your other hand under the line card to support its weight. Avoid touching the line card printed circuit board, its components, or its edge connector pins (see Figure 7-32c).
Upgrading Memory on a Line Card Removing a DIMM from a Line Card Line card memory consists of DRAM DIMMs for the line card’s processor, as well as SDRAM DIMMs for the line card’s transmit and receive buffers. The locations of the DIMM sockets for these two types of line card memory are shown in Figure 7-30. The following guidelines apply to line card processor DRAM: • • • The P4 DIMM0 socket must always be populated. The P4 DIMM1 socket can remain empty. The DRAM DIMMs must be 3.3-volt devices.
Upgrading Memory on a Line Card Step 5 As one end of the DIMM is released, grasp the top corners of the DIMM with the thumb and forefinger of each hand and pull the DIMM completely out of its socket. Note Handle the DIMM only by its top corners; do not touch the memory chips or the keyed insertion fingers along the bottom of the DIMM (see Figure 7-32). Step 6 Immediately place the module in an antistatic bag to protect it from ESD damage.
Upgrading Memory on a Line Card Step 5 Gently insert the DIMM into the socket until the release lever is flush against the side of the socket. If necessary, rock the DIMM back and forth gently to ensure that it is fully seated. Caution When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If you damage a DIMM socket, you must return the line card to the supplier for repair. Step 6 Verify that the release lever is flush against the side of the socket.
Upgrading Memory on a Line Card Step 6 Step 7 Replace the vertical cable-management bracket, as follows: (a) Unhook the line card vertical cable-management bracket from the horizontal cable tray. (b) Position the bracket over the front of the line card faceplate. (c) Tighten the two captive screws at the top and bottom of the vertical cablemanagement bracket to secure it to the line card. Restore the network interface cables to their original ports on the line card faceplate.
Upgrading Memory on the RP If the system fails to restart properly after several attempts and you are unable to resolve the problem, contact your Cisco service representative for assistance. Before calling, however, make note of any console error messages, unusual LED states, or other system indications or behaviors that might help to resolve the problem. The time that the system requires to initialize may vary with different router configurations and memory configurations.
