2 CHAPT E R Preparing to Install Cisco 4000 Series Routers This chapter includes information you need before you install your Cisco 4000 series router. It includes the following sections: • • • • • • Safety Recommendations General Site Requirements Installation Checklist Site Log Required Tools and Equipment Inspecting the System Safety Recommendations The following guidelines will help to ensure your safety and protect the equipment.
Safety Recommendations • Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves. Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.
Safety Recommendations • • Never assume that power is disconnected from a circuit. Always check. • If an electrical accident occurs, proceed as follows: Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds. — Use caution; do not become a victim yourself. — Turn off power to the system. — If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and then call for help.
General Site Requirements Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.
General Site Requirements Site Configuration Precautions The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures: • Remember that electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Ensure that the room in which your system operates has adequate circulation.
General Site Requirements Equipment Racks The following tips will help you plan an acceptable equipment rack configuration: • Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. • When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or the exhaust ports.
Installation Checklist Installation Checklist The Installation Checklist lists the procedures for initial hardware installation of a new router. Make a copy of this checklist and mark the entries as you complete each procedure. Include a copy of the checklist for each system in your Site Log. (See the next section “Site Log.
Site Log Site Log The Site Log provides a historical record of all actions relevant to the router. Keep it in an accessible place near the chassis where anyone who performs tasks has access to it. Use the Installation Checklist to verify steps in the installation and maintenance of your router. Site Log entries might include the following: • Installation progress—Make a copy of the Installation Checklist and insert it into the Site Log. Make entries as each procedure is completed.
Inspecting the System In addition, you might need the following additional external equipment: • • Data service unit (DSU) to connect each serial port to an external network. • • • Ethernet transceiver. To connect a serial port to a T1 network, you need a T1 channel service unit/data service unit (CSU/DSU) that converts the High-Level Data Link Control (HDLC) synchronous serial data stream into a T1 data stream with the correct framing and ones density.
Inspecting the System • • • This publication Cisco Information Packet Optional companion publications, or the Cisco Connection Documentation, Enterprise Series CD, as specified on your order Inspect all items for shipping damage. If anything appears damaged, or if you encounter problems when installing or configuring your system, contact a customer service representative. Also, please complete and mail your product registration (see the publication Cisco Information Packet).
3 CHAPT E R Configuring the Cisco 4000 Series Chassis This chapter describes the tasks that should be completed before you connect a Cisco 4000 series router to your network.
Accessing the Internal Components of the Router Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.
Accessing the Internal Components of the Router Warning Before releasing the safety latch, support the component tray from underneath, either on your work surface or with your hands, to prevent personal injury. (See Figure 3-1.) Figure 3-1 Component Tray Removal for Chassis With a Safety Latch Step 6 Support the component tray with one hand, push down on the safety latch tab, and pull the component tray out the rest of the way. Step 7 Set the component tray on your work surface.
Accessing the Internal Components of the Router Step 1 Turn OFF the system power. Step 2 Put on your ESD-preventive wrist strap. Step 3 Remove all network and power cables. Step 4 Loosen the nonremovable chassis release screw on the rear panel of the chassis. (See Figure 3-2.) Figure 3-2 Component Tray Removal for Chassis Without a Safety Latch Caution Support the component tray from underneath, either on your work surface or with your hands, to prevent it from falling.
Replacing Network Processor Modules Step 5 Pull on the handle located on the upper right corner of the chassis to slide the component tray out of the chassis shell while you support the component tray with one hand. Step 6 Set the component tray on your work surface. Replacing Network Processor Modules When you have removed the component tray from the router, you can remove or add network processor modules.
Replacing Network Processor Modules Figure 3-3 Cisco 4000-M Component Tray—Typical of Cisco 4000 Series Caution Do not wiggle the handle when handling the network processor module, and do not exert any side-to-side pressure because the handle might work loose and damage the network processor module.
Replacing Network Processor Modules Figure 3-4 Network Processor Module Components Caution If any of the network processor module cards have daughter cards projecting at right angles to the module (see Figure 3-5), be careful not to cause the module to bow during installation; otherwise the daughter cards can become disconnected. If this happens, carefully reseat the daughter card connectors by handling the card by its edges without touching any of the components on the card.
Replacing Network Processor Modules Figure 3-5 Network Processor Module Daughter Card Installation Note See the appendix “Cabling Specifications for Cisco 4000 Series Routers” for network connection pinout information. Installing Network Processor Modules Take the following steps to install a network processor module: Step 1 Hold the network processor module by its handle, align it with the grooves in the chassis (not shown) and over its connector, and push the module lightly against the chassis wall.
Replacing the Component Tray Step 3 Replace the module mounting screw in its place on the end of the network processor module. (See Figure 3-4.) Caution Do not overtighten the module mounting screw. The network processor module or the underlying motherboard could be damaged. The maximum screw torque is 7 inch-lb. Step 4 Replace the external rear mounting screws, if used, to attach the module to the rear of the chassis.

Network Connection Considerations used. If you understand the electrical problems that might arise and can compensate for them, you can get good results with rates and distances greater than those shown. However, do so at your own risk.

Network Connection Considerations Figure 4-14 EIA/TIA-232 Adapter Cable Connectors, Network End DCE H1343a DTE EIA/TIA-449 Connections EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423) transmissions, is a faster (up to 2 Mbps) version of EIA/TIA-232 that provides more functions and supports transmissions over greater distances.
Network Connection Considerations V.35 Connections The V.35 interface is recommended for speeds up to 48 kbps, although in practice it is used successfully at 4 Mbps. The network end of the V.35 adapter cable provides a standard 34-pin Winchester-type connector. (See Figure 4-16.) V.35 cables are available with a standard V.35 plug or receptacle in either DTE or DCE mode. Figure 4-16 V.35 Adapter Cable Connectors, Network End DCE H1616a DTE X.21 Connections The X.
Network Connection Considerations Figure 4-17 X.21 Adapter Cable Connectors, Network End 1 8 15 9 DCE H1346a DTE EIA-530 Connections EIA-530, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller, DB-25 connector used for EIA/TIA-232, instead of the 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423.
Network Connection Considerations • Plant cabling can emit radio frequency interference (RFI) if it is unshielded for a distance exceeding those recommended by the standard. • Strong electromagnetic interference, especially as caused by lightning or radio transmitters, can destroy the EIA/TIA-232 drivers and receivers in a router. If you use twisted-pair cables in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference.

To prevent damage from stress or from ESD, do not exert force against the two LED daughter cards, and do not touch the components on the cards.
Network Connection Considerations If the network processor module is operating as DTE in NRZI mode, the sense of the dte-invert-timing command must be manually changed. For instance, if the command no dte-invert-timing was previously entered in the configuration file, then dte-invert-timing must be configured for the module to operate as DTE in NRZI mode. To set the jumpers for NRZI, move the jumpers to the position shown in Figure 4-23 using the orientation shown in Figure 4-22.

Network Connection Considerations Warning Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages are also accessible on the BRI module in the area of the BRI port (RJ-45 connector), even when power is turned OFF. (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.”) The specifications for the BRI cable are given in Table 4-8.
Network Connection Considerations controller provides up to 24 virtual channels. Each virtual channel is presented to the system as a serial interface that can be configured individually. This interface is the physical media that supports ISDN PRI. The CT1/PRI network processor module, shown in Figure 4-41, provides a controller for transmitting and receiving data bidirectionally at the T1 rate of 1.544 Mbps. For wide-area networking, the CT1/PRI module can function as a concentrator for a remote site.
Network Connection Considerations T1 Cabling For the CT1/PRI network processor module, two standard T1 serial cables are available from Cisco Systems: null-modem and straight-through. A straight-through cable connects your router to an external CSU. Null-modem cables are used for back-to-back operation and testing. The cables have male 15-pin DB connectors at each end to connect the CT1/PRI module to the external CSU.
Network Connection Considerations The CE1/PRI network processor module, shown in Figure 4-43, provides a controller for transmitting and receiving data bidirectionally at the E1 rate of 2.048 Mbps. For wide-area networking, the CE1/PRI module can function as a concentrator for a remote site. Following are the E1 specifications: • • Transmission bit rate: 2.048 Mbps ± 50 ppm • • Input port specifications: see G.703 / Section 6.3 (ITU-T specification) Output port specifications: see G.703 / Section 6.
Network Connection Considerations CE1/PRI Network Processor Module Jumper Settings The jumpers on the CE1/PRI network processor module set capacitive coupling between the transmit or receive shield and chassis ground, and the cable resistance (120 ohm or 75 ohm). By default, the CE1/PRI network processor module is set with capacitive coupling between the receive (RX) shield and chassis ground. This provides direct current (DC) isolation between the chassis and external devices, as stated in the G.

Network Connection Considerations The ATM modules provide an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps in each direction (RX and TX); the actual rate is determined by the physical layer interface module (PLIM) and ATM network technology (by the specific physical layer).
Network Connection Considerations For a description of the common ATM terms and acronyms, see the publication Internetworking Terms and Acronyms. All ATM interfaces are full-duplex. You must use the appropriate ATM interface cable and accessories to connect the ATM network processor module with an external ATM network. The ATM interface cable is used to connect your router to an ATM switch, or to connect two router ATM interfaces back to back.

Network Connection Considerations ATM SONET Distance Limitations The SONET specification for fiber-optic transmission defines two types of fiber: single mode and multimode. Single-mode fiber is capable of higher bandwidth and greater cable run distances than multimode fiber. The typical maximum distances for single-mode and multimode transmissions, as defined by SONET, are in Table 4-10.
Network Connection Considerations Attenuation is significantly lower for optical fiber than for other media. For multimode transmission, chromatic and modal dispersion reduce the available power of the system by the combined dispersion penalty, measured in decibels (dB). The power lost over the data link is the sum of the component, dispersion, and modal losses. Table 4-11 lists the factors of attenuation and dispersion limit for typical fiber-optic cable.
Network Connection Considerations The power margin calculation is derived from the power budget and subtracts the link loss, as follows: M = PB – LL If the power margin is positive, as a rule, the link will work. Table 4-12 lists the factors that contribute to link loss and the estimate of the link loss value attributable to those factors. After calculating the power budget minus the data link loss, the result should be greater than zero.
Network Connection Considerations Multimode Power Budget Example The following is an example multimode power budget, based on the following variables, and calculated to ensure sufficient power for transmission: Length of multimode link = 3 kilometers (km) 4 connectors 3 splices Higher order loss (HOL) Clock recovery module (CRM) Estimate the power budget as follows: PB = 11.5 dB – 3 km (1.0 dB/km) – 4 (0.5 dB) – 3 (0.5 dB) – 0.5 dB (HOL) – 1 dB (CRM) PB = 11.5 dB – 3 dB – 2 dB – 1.5 dB – 0.
Network Connection Considerations Single-Mode Transmission The single-mode signal source is an injection laser diode. Single-mode transmission is useful for longer distances, because there is a single transmission path within the fiber and smear does not occur. In addition, chromatic dispersion is also reduced because laser light is essentially monochromatic. The maximum overload specification on the single-mode receiver is –14 decibels (dB).

Booting the Router for the First Time Take the following steps to power up the router: Step 1 If you have an AC-powered system, plug the system power cord into a 3-terminal, single-phase power source that provides power within the acceptable range (100–240 VAC, 50–60 Hz, 3.0–1.5A). Step 2 If you have a DC-powered system, make sure to connect the input power supply as described in the section “DC-Input Power Supply Connection” in the chapter “Router Installation.
Configuring the Router You use two commands to do this: • • enable secret password (which is a very secure, encrypted password) enable password (which is a less secure, or nonencrypted password) You must enter an enable secret password to gain access to privileged-level commands. For maximum security, the passwords should be different.
Configuring the Router Before continuing the configuration process, check the current state of the router by entering the show version command. The show version command will display the release of Cisco IOS software that is available on the router. Configuring the Router Using Configuration Mode You can configure the router manually if you prefer not to use the setup facility or AutoInstall.
Configuring the Router Step 4 Enter the command config terminal at the enable prompt to enter configuration mode: Router# config terminal You can now enter any changes to the configuration that you want to make. Press Ctrl-Z to exit configuration mode. To see the currently operating configuration, enter the command show running-config at the enable prompt: Router# show running-config To see the configuration in nonvolatile random-access memory (NVRAM), enter the command show config at the enable prompt.
Configuring the Router • User Datagram Protocol (UDP) broadcasts to and from the router and the TCP/IP host must be enabled. This functionality is coordinated by your system administrator at the site where the TCP/IP host is located. You should not attempt to use AutoInstall unless the required files have been installed on the TCP/IP host. Take the following steps to prepare your router for the AutoInstall process: Step 1 Attach the synchronous serial cable to the router.
Configuring the Router Note You can run the setup facility any time you are at the enable prompt by entering the setup command. Configuring the Global Parameters When you first start the setup program you must configure the global parameters, which are used for controlling system-wide settings. Note The screen displays shown in this section may vary from those displayed on your console terminal, depending on the configuration of your router.
Configuring the Router Step 3 Enter yes (the default) or press Return when you are asked if you would like to enter the configuration dialog and if you would like to see the current interface summary.
Configuring the Router Enter yes or no to accept or refuse Simple Network Management Protocol (SNMP) management: Configure SNMP Network Management? [no]: SNMP is the most widely supported open standard for network management. It provides a means to access and set configuration and run-time parameters of routers and communication servers. SNMP defines a set of functions that can be used to monitor and control network elements.

Additional Configuration Tasks • • Configuring the Asynchronous/Synchronous Serial Interfaces Configuring G.703/G.704 Interfaces Configuring the Ethernet Interface If your router has an Ethernet network processor module installed, you need to configure the Ethernet ports. Take the following steps to configure the Ethernet interfaces: Step 1 Respond as follows to the prompts, substituting the correct IP address and number of subnet bits for your site.
Additional Configuration Tasks Step 3 If you are going to enable IPX on this interface, enter the unique IPX network number: Configure IPX on this interface? [no]: yes IPX network number [1]: B001 Configure XNS on this interface? [no] Step 4 Repeat Step 1 through Step 3 to configure each Ethernet interface in your router. You must also select the type of media connection to the module by entering media-type commands in the router’s configuration file.
Additional Configuration Tasks For more information about the media-type command, refer to the Cisco IOS configuration guides and command references. Configuring the T1 Interface If you installed a new channelized T1/ ISDN PRI (CT1/PRI) network processor module, or if you want to change the configuration of an existing network processor module, you must enter configuration mode to configure or reconfigure the interface.
Additional Configuration Tasks Step 3 Specify the clock source for the module. The clock source command determines which end of the circuit provides the clocking: Router(config-controller)# clock source line Note The clock source should only be set to use the internal clocking for testing the network or if the full T1 line is used as the channel group. Only one end of the T1 line should be set to internal.
Additional Configuration Tasks Router(config-if)# ip address 10.1.15.1 255.255.255.0 Router(config-if)# Step 9 Add any additional configuration commands required to enable routing protocols and adjust the interface characteristics. Refer to the Cisco IOS configuration guides and command references for more information on configuration subcommands. Step 10 When you have completed the configuration, press Ctrl-Z to exit configuration mode.
Additional Configuration Tasks • • IP addresses if you will configure the interfaces for IP routing Whether the new interface will use bridging Take the following steps to complete a basic E1 configuration. Step 1 At the privileged-level prompt, enter the configuration terminal command to enter configuration mode and specify that the console terminal will be the source of the configuration commands: Router# conf t Enter configuration commands, one per line. End with CNTL/Z.
Additional Configuration Tasks Router(config-if)# ip address 10.1.15.1 255.255.255.0 Router(config-if)# Step 7 Add any additional configuration subcommands required to enable routing protocols and adjust the interface characteristics. Refer to the Cisco IOS configuration guides and command references for more information on configuration subcommands. Step 8 When you have completed the configuration, press Ctrl-Z to exit configuration mode.
Additional Configuration Tasks Class B network is 172.16.0.0, 8subnet bits; mask is 255.255.255.0 Step 2 Repeat Step 1 for each BRI interface installed in your router. Configuring the ATM Network Processor Module Interface If you installed a new ATM network processor module or if you want to change the configuration of an existing module, you must enter the configuration mode.
Additional Configuration Tasks If you are using a SONET interface, there is only one framing type, STM-1, which is the default and need not be entered: Router(config-if)# atm sonet stm-1 If you are specifying the framing type for an E3 interface, there are two framing types: G.751 ADM (entered as g751adm) and G.832 ADM (entered as g832adm).
Additional Configuration Tasks Step 8 Create the mapping of protocol addresses to PVCs. Map lists are used to assign protocol addresses to virtual circuits (VCs): Router(config-if)# map-list list1 Router(config-map-list)# ip 1.1.1.2 atm-vc 1 broadcast Router(config-map-list)# ip 1.1.1.3 atm-vc 2 broadcast Step 9 Press Ctrl-Z to complete the configuration.
Additional Configuration Tasks Router(config-if)# atm framing g832adm If you are specifying the framing type for a DS-3 interface, there are three framing types: C-bit PLCP (entered as cbitplcp), M23 ADM (entered as m23adm) and M23 PLCP (entered as m23plcp). Router(config-if)# atm framing m23adm Step 4 Assign protocol addresses to the interface: Router(config-if)# ip address 10.1.15.1 255.255.255.
Additional Configuration Tasks Step 12 Exit the privileged level and return to the user level: Router# disable Configuring the Synchronous Serial Interfaces If you have a serial network processor module installed, you need to configure the synchronous serial interfaces to allow connection to WANs through a CSU/DSU.
Additional Configuration Tasks Configuring Timing (Clock) Signals for Serial Interfaces All interfaces support both data terminal equipment (DTE) and DCE modes, depending on the mode of the interface cable attached to the port. To use a port as a DTE interface, connect a DTE adapter cable to the port. When the system detects the DTE mode cable, it automatically uses the external timing signal.
Additional Configuration Tasks Use the no clockrate command to remove the clock rate for DTE operation. Following are the acceptable clock rate settings: 1200 2400 4800 9600 19200 38400 56000 64000 72000 125000 148000 500000 800000 1000000 1300000 2000000 4000000 Speeds above 64 kbps (64000) are not supported for EIA/TIA-232. On all interface types, if your cable is too long, faster speeds might not work.
Additional Configuration Tasks To turn off this command, use the no dce-terminal-timing-enable command. When the serial port is a DTE, the invert-txc command inverts the TXC clock signal it receives from the remote DCE. When the serial port is a DCE, this command inverts the clock signal to the remote DTE port. Use the no invert-txc command to change the clock signal back to its original phase.
Additional Configuration Tasks Calculating CRCs on Cisco 4000 Series Serial Interfaces On Cisco 4000 series routers, all serial interfaces support CRC-ITU-T, a 16-bit cyclic redundancy check (CRC). CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The sender of a data frame divides the bits in the frame by a predetermined number to calculate a remainder or frame check sequence (FCS).
Additional Configuration Tasks Router(config-if)# physical-layer async Configure other asynchronous parameters according to your needs, for example: Router(config-if)# async mode dedicated Router(config-if)# async default routing Step 4 To configure asynchronous line settings, use the line async command.
Additional Configuration Tasks Note For older versions of software, use the write mem command to write the new configuration to memory. Step 7 Enter the disable command to return to the user level: Router# disable Router> Step 8 Enter the show commands to check the configuration of the interface. Note On Step 2, the serial interface numbers for the low-speed ports can be 2–17 or 20–35 as previously described in Table 4-4. Configuring G.703/G.
Additional Configuration Tasks • Clock source operation (line or internal) Note Always enter the clear interface command after altering the configuration of an interface, particularly after changing a time slot or CRC-4 setting. Configuring Framed and Unframed Mode for E1-G.703/G.704 Interfaces The E1-G.703/G.704 interfaces support both framed (G.704) and unframed (G.703) modes of operation; the default is for unframed operation. To enable framed operation, you must specify the start and stop slots.
Checking the Router Configuration Configuring CRC-4 for E1-G.703/G.704 Interfaces CRC-4 is a 4-bit error checking technique that uses a calculated numeric value to perform an ongoing data integrity check and detect errors in transmitted data. The E1-G.703/G.704 network processor module supports CRC in framed mode only. By default, CRC-4 is not enabled. To enable CRC-4 on the E1 interface, specify the port address of the interface followed by the command crc4.
Checking the Router Configuration Received 0 broadcasts, 0 runts, 0 giants 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 145 packets output, 185562 bytes, 0 underruns 0 output errors, 0 collisions, 1 interface resets, 0 restarts 880 carrier transitions The field underrun in the output of the show interface command may be nonzero in approximately one of 250,000 packets.
Saving the Router Configuration If the cable is DCE, the output of the show controller command displays the clock rate. For complete command descriptions and instructions, refer to the Cisco IOS configuration guides and command references.

D APPEND IX Cisco 4000 Series Virtual Configuration Register This appendix describes the Cisco 4000 series virtual configuration register, the factory-default settings, and the procedures for changing those settings. Virtual Configuration Register Settings The Cisco 4000 series has a 16-bit virtual register, which is written into the nonvolatile random access memory (NVRAM).
Virtual Configuration Register Settings Table D-1 Virtual Configuration Bit Meanings Bit No.
Virtual Configuration Register Settings Take the following steps to change the configuration register while running the Cisco IOS software: Step 1 Enter the enable command and your password to enter the privileged level, as follows: router> enable Password: router# Step 2 At the privileged-level system prompt (router #), enter the command configure terminal. You will be prompted as shown in the following example: router# configure term Enter configuration commands, one per line.
Virtual Configuration Register Settings Configuring the Boot Field The lowest four bits of the processor configuration register (bits 3, 2, 1, and 0) form the boot field. (See Table D-2.
Virtual Configuration Register Settings If you set the boot field value to a value of 2 through F, and there is a valid system boot command stored in the configuration file, the router boots the system software as directed by that value. (See Table D-3.) If you set the boot field to any other bit pattern, the router uses the resulting number to form a default boot filename for booting from a network (TFTP) server.
Virtual Configuration Register Settings Table D-3 Default Boot Filenames Action/File Name Bit 3 Bit 2 Bit 1 Bit 0 bootstrap mode 0 0 0 0 ROM software 0 0 0 1 cisco2-4000 or cisco2-4500 0 0 1 0 cisco3-4000 or cisco3-4500 0 0 1 1 cisco4-4000 or cisco4-4500 0 1 0 0 cisco5-4000 or cisco5-4500 0 1 0 1 cisco6-4000 or cisco6-4500 0 1 1 0 cisco7-4000 or cisco7-4500 0 1 1 1 cisco10-4000 or cisco10-4500 1 0 0 0 cisco11-4000 or cisco11-4500 1 0 0 1 cisco12-4000
Virtual Configuration Register Settings Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the console Break key. Clearing bit 8 causes the processor to interpret Break as a command to force the system into the bootstrap monitor, halting normal operation. A Break can be sent in the first 60 seconds while the system reboots, regardless of the configuration settings. Bit 10 controls the host portion of the Internet broadcast address.
Virtual Configuration Register Settings Table D-5 System Console Terminal Baud Rate Settings Baud Bit 12 Bit 11 9600 0 0 4800 0 1 1200 1 0 2400 1 1 Enabling Booting from Flash Memory To enable booting from Flash memory, set bits 3, 2, 1, and 0 to a value between 2 through 15. To specify a filename to boot, enter the system software configuration boot system flash filename command in the configuration file.
APPEND IX E Cisco 4000-M ROM Monitor This appendix describes the Cisco 4000-M ROM monitor, which is also known as the bootstrap program. The ROM monitor can help you isolate or rule out hardware problems encountered when installing your router. A summary of the ROM monitor diagnostic tests and command options is provided. Entering the Cisco 4000-M ROM Monitor Program The ROM monitor diagnostics help initialize the processor hardware and boot the main operating system software.
Entering the Cisco 4000-M ROM Monitor Program Timesaver Break (system interrupt) is always enabled for 60 seconds after rebooting the system, regardless of whether Break is configured to be off by setting the configuration register. During the 60-second window, you can use Break to get to the ROM monitor prompt.
Entering the Cisco 4000-M ROM Monitor Program over the network using the TFTP. You can also include a second argument, host, which is the Internet address or name of a particular server host. You must enter i and press Return before entering b. The various forms of the b command follow: b—Boots the default system software from ROM. b filename [host]—Boots from a network server (netboots) using TFTP.
Entering the Cisco 4000-M ROM Monitor Program Table E-1 Monitor Command o Command Options Function o Displays the virtual configuration register currently in effect, with a description of the bits o/r Resets the virtual configuration register to the defaults as follows: 9600-baud console UART1 speed Break/abort has no effect Ignore the system configuration Boot from ROM o/r 0xvalue Sets the virtual configuration register to the (hex) value, value 1.
Entering the Cisco 4000-M ROM Monitor Program The time to run a diagnostic is memory-size dependent. It will take a minimum of ten minutes. If the program encounters memory problems, it will display appropriate error messages on the console terminal. Be sure to reinitialize the processor before booting the system by entering i at the ROM monitor prompt. Running the Diagnostics Take the following steps to run the ROM monitor diagnostics: Step 1 Turn OFF the unit. Step 2 Restart the router.

APPEND IX F Cisco 4500-M and Cisco 4700-M ROM Monitor This appendix describes the Cisco 4500-M and Cisco 4700-M ROM monitor, the first software to run when the router is powered up or reset. The Cisco 4500-M and Cisco 4700-M ROM monitor supports more features than the familiar Cisco 4000-M ROM monitor. The ROM Monitor can help you isolate or rule out hardware problems encountered when installing your router. A summary of the ROM monitor diagnostic tests and command options is provided.
Entering the ROM Monitor Program Timesaver Break (system interrupt) is always enabled for 60 seconds after rebooting the system, regardless of whether Break is configured to be off by setting the configuration register. During the 60-second window, you can use Break to get to the ROM monitor prompt.
Entering the ROM Monitor Program The following case-sensitive ROM monitor commands are among the most useful: • help—The help command prints a summary of the ROM monitor commands to the console screen.This is the same output as entering ?. • boot or b—Boot an image. The boot command with no arguments will boot the first image in boot Flash memory. You can include an argument, filename, to specify a file to be booted over the network using the Trivial File Transfer Protocol (TFTP).
Entering the ROM Monitor Program • dir—Lists the files on the named device, dir device, where the device is flash or bootflash; lists the available files on that device. For example: rommon 11 > dir flash: File size Checksum File name 2229799 bytes (0x220627) 0x469e C4500-k Debugging Commands Most of the debugging commands are functional only when the Cisco IOS software has crashed or is aborted.
Entering the ROM Monitor Program • meminfo—Displays the size in bytes, the starting address, the available range of the main memory, the starting point and size of packet memory, and the size of nonvolatile random-access memory (NVRAM). rommon 9 > meminfo Main memory size: 8 MB. Packet memory size: 4 MB Available main memory starts at 0xa000e001, size 0x7f1fff Packet memory starts at 0xa8000000 NVRAM size: 0x20000 Configuration Register The configuration register resides in NVRAM.
