Appendix A Technical Specifications Product Architecture Warning Exhaust from other equipment vented directly into the Cisco 12404 Internet router air inlet may cause an over-heat condition. Install the router so that it is protected from a direct flow of hot air from other equipment. AC-Powered Routers At sites where the Cisco 12404 router operates with AC PEMs, observe the following guidelines.

Appendix A Technical Specifications Product Architecture Gigabit Route Processor This section provides an overview of the GRP (Figure A-2) and its use as the main system processor for the Cisco 12404 Internet router. This section provides information on the following GRP functionality.
Appendix A Technical Specifications Product Architecture The MBus connection allows the GRP to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations. The GRP plugs into any slot in the card cage in the Cisco 12404 Internet router. The router is shipped with 20MB of Flash memory as the default configuration. GRP Memory Memory components of the GRP are listed in Table A-4.
Appendix A Technical Specifications Product Architecture The Cisco IOS software images that run the Cisco 12404 router reside in Flash memory, which is located on the GRP in the form of a single in-line memory module (SIMM), and on up to two (PCMCIA) cards (called Flash memory cards) that insert in the two PCMCIA slots on the front of the GRP.
Appendix A Technical Specifications Product Architecture SRAM The SRAM provides secondary CPU cache memory. The standard GRP configuration is 512 KB. The principle function of SRAM is to act as a staging area for routing table update information to and from the line cards. SRAM is not able to be upgraded or configured.
Appendix A Technical Specifications Product Architecture LED Types Table A-6 describes the types of system status light emitting diodes (LED) used on the GRP. Table A-6 System Status LED Types, Description, and Power Source LEDs Description and Power Source 2 PCMCIA Activity LEDs (one per PCMCIA slot) light when the slot is accessed. The LEDs receive power from the switched slot voltage. 4 RJ-45 Ethernet port LEDs are used in conjunction with the RJ-45 Ethernet connector.
Appendix A Technical Specifications Product Architecture Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the EIA/TIA. The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment interface. The auxiliary port supports flow control and can be used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

Appendix A Technical Specifications Product Architecture SDRAM SDRAM—The SDRAM on the PRP stores routing tables, protocols, and network accounting applications; it also 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. Supported memory configurations are listed in Table A-8.
Appendix A Technical Specifications Product Architecture NVRAM The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 2 MB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of five years.

Appendix A Technical Specifications Product Architecture LED Types Table A-10 lists system status light emitting diodes (LED) used on the PRP. Table A-10 System Status LED Types, Description, and Power Source LEDs Description and Power Source 2 PCMCIA Activity LEDs (one per PCMCIA slot) light when the slot is accessed. The LEDs receive power from the switched slot voltage. 4 RJ-45 Ethernet port LEDs are used in conjunction with the RJ-45 Ethernet connector.
Appendix A Technical Specifications Product Architecture Ethernet Port The PRP includes two Ethernet ports, both using an 8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections. Note The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable. Line Cards The Cisco 12404 router is shipped with up to 3 installed line cards that provide a variety of network media types (based on the order).
Appendix A Technical Specifications Product Architecture Line cards installed in the Cisco 12404 router support online insertion and removal, which means you can remove and replace (hot-swappable) a line card while the router remains powered on. Caution To ensure adequate airflow through the card cage, empty card slots must have a card blank installed. Consolidated Switch Fabric Status An OK/Fail pair of LEDs are provided to indicate the status of the Alarm MBus and Fabric MBus.
Appendix A Technical Specifications Product Architecture MBus Module Port Pin Assignments Twenty general purpose pins and four analog input pins on the MBus module are used for this design. CSF Functionality The CSF circuity provides synchronized speed interconnections for the line cards and the RP (Figure A-5). The CSF circuitry consists of clock and scheduler, and switch fabric functionality; is contained on one card, housed in the bottom slot in the chassis.
Appendix A Technical Specifications Product Architecture Scheduler The scheduler handles requests from the line cards for access to the CSF. When the scheduler receives a request from a line card for CSF access, the scheduler determines when to allow the line card access to the CSF. Switch Fabric Switch fabric circuitry carries the user traffic between line cards or between the RP and the line cards.
Appendix A Technical Specifications Product Architecture Connect each AC PEM to a separate AC power source. A power factor corrector (PFC) allows the PEM to accept AC power source voltage from an AC power source nominally operating between 100 to 120 VAC, 15-Amp service in North America; and a range of 185 to 264 VAC, 10-Amp service, in an international environment.
Appendix A Technical Specifications Product Architecture A PFC allows the PEM to accept DC power source voltage from an AC power source operating between 100 to 120 VAC, 15-Amp service in North America; and a range of 185 to 264 VAC, 10-Amp service in an international environment. Note Attach each DC PDU be connected to an independent power source for full redundancy. Use an uninterruptable power source (UPS) to protect against power failures at your site.
Appendix A Technical Specifications Fan Tray Assembly Caution Warning The DC PEM and DC PDU assembly weighs 14.0 pounds (6.35 kg.). Use two hands when handling the power supply. Power to your router must be Off and all cables disconnected before you connect the DC PDU. The DC PDU is not a hot-swappable, field replaceable unit. Fan Tray Assembly The Cisco 12404 router has one fan tray (Figure A-8). Facing the rear of the chassis the fan tray assembly is located on the right side of the chassis.
Appendix A Technical Specifications Fan Tray Assembly Warning Allow sufficient air flow by maintaining 6 inches (15.24 cm) of clearance at both the inlet and exhaust openings on the chassis because exhaust from other equipment vented directly into the router air inlet may cause an over-heat condition. The fans draws room air in through an air filter on the opposite side of the chassis. See Figure A-9.
Appendix A Technical Specifications Air Filter If the air temperature inside the RP and line card cage rises the system environmental monitor shuts down all internal power to prevent equipment damage from excessive heat. If the system detects that one of the fans within the fan tray assembly has failed, it displays a warning message on the console screen. If multiple fans fail, the system will shut down to prevent equipment damage.
Appendix A Technical Specifications Chassis Cable-Management System Chassis Cable-Management System The Cisco 12404 Internet router chassis cable-management system organizes the interface cables entering and exiting the system, keeping them free of sharp bends (excessive bending in an interface cable can cause performance degradation) and out of the way. See Figure A-11.
Appendix A Technical Specifications Maintenance Bus directly from the power supply and performs the functions of power-up/down control, device discovery, code download, diagnostics, and environmental monitoring and alarms. Power-On/Off Control Based on commands it receives from its on-board EPROM and from the master RP, each MBus module directly controls the DC-DC converters on the component to which it is mounted. Each MBus module is tied directly to +5 VDC from the power supply.
