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.
• A power factor corrector (PFC) allows the PEM to accept AC power source
voltage from an AC power source operating between 100–120 VAC, 15–Amp
service in North America; and a range of 185–264 VAC, 10–Amp service, in
an international environment.
• All AC PEM power cords measure 14 feet (4.3 meters).
• Provide a dedicated power source for each PEM installed in the router.
• Install an uninterruptable power source where possible.
AC Power Plugs
Different styles of AC input power cords are shown in Figure A-1.

Route Processor
Each Cisco 12404 Internet router 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. The RP
also performs general maintenance functions, such as diagnostics, console
support, and line card monitoring.
Two types of RPs are available for the Cisco 12404 Internet router:
• Gigabit Route Processor (GRP)
• Performance Route Processor (PRP)

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.
• GRP memory
• System status LEDs
• Soft reset switch
• PCMCIA slots
• Asynchronous serial ports
Figure A-2 Gigabit Route Processor
The following are primary functions of the GRP.
• Loading the Cisco IOS software to all of the installed line cards at power on
• Providing a console (terminal) port for router configuration
• Providing an auxiliary port for other external equipment (such as modems)
• Providing an IEEE 802.3, 10/100-megabit-per-second (Mbps) Ethernet port
for Telnet functionality
• Running routing protocols
• Building and distributing routing tables to the line cards
• Providing general system maintenance functions for the router
The GRP communicates with the line cards either through the CSF or through the
maintenance bus (MBus). The CSF 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. 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.

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. Storing the Cisco
IOS images in Flash memory enables you to download and boot from upgraded
Cisco IOS images remotely or from software images resident in GRP Flash
memory.
The Cisco 12404 router supports system software downloads for most Cisco IOS
software upgrades, which enables you to remotely download, store, and boot from
a new Cisco IOS image. See Figure A-2.
DRAM
The EDO DRAM on the GRP stores routing tables, protocols, and network
accounting applications; it also runs the Cisco IOS software. The default GRP
DRAM configuration is 64 megabytes of EDO DRAM, which you can increase up
to 256 MB through DRAM upgrades. The Cisco IOS software runs from within
GRP DRAM. Tab le A- 5 lists the DRAM configurations and upgrades.
Caution To prevent memory problems, DRAM DIMMs must be 3.3-volt, 60-nanosecond
devices. Do not attempt to install other devices in the DIMM sockets.
