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)

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. Table 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.

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.
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
5years.NVRAMisnot able to be upgraded or configured
Caution Before you replace the GRP in the system, back up the running configuration to a
Trivial File Transfer Protocol (TFTP) file server or an installed Flash memory
card so you can retrieve it later.
If the configuration is not saved, the entire configuration is lost inside the
NVRAM on the removed GRP and you must re-enter the entire configuration
manually.
This procedure is not necessary if you are temporarily removing a GRP; lithium
batteries retain the configuration in memory until you replace the GRP in the
router.
Flash Memory
Both the onboard and PCMCIA card-based Flash memory allow you to remotely
load and store multiple Cisco IOS software and microcode images. You can
download a new image over the network or from a local server and then add the
new image to Flash memory or replace the existing files. You can then boot the
routers either manually or automatically from any of the stored images. Flash
memory also functions as a TFTP server to allow other servers to boot remotely
from stored images or to copy them into their own Flash memory.
PCMCIA Slots
The GRP has two PCMCIA slots. Either slot can support a Flash memory card or
an input/output (I/O) device as long as the device requires only +5 VDC.

LED Types
Table A-6 describes the types of system status light emitting diodes (LED) used
on the GRP.
Asynchronous Serial Ports
Two asynchronous serial ports on the GRP, the console and auxiliary ports, allow
you to connect external devices to monitor and manage the system.
The consoleport is an Electronics Industries Association/Telecommunications
Industry Association (EIA/TIA)-232 receptacle (RS-232 female) that provides a
data circuit-terminating equipment (DCE) interface for connecting a console
terminal.
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. The LEDs indicate link activity, collision detection, data
transmission, and data reception.
When the MII Ethernet port is in use, the LEDs are disabled.
2 RJ-45 or MII Ethernet port select 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.
Alphanumeric displays These alphanumeric LED displays are controlled directly by the MBus and
provide information about the system status during the boot process.
Alphanumeric displays are organized as two rows of four characters each.
The displays’ content is controlled by the MBus module software. Both
rows of the display are powered by the MBus module.
After the boot process, the LEDs are controlled by Cisco IOS software
through the MBus, and display messages designated by Cisco IOS
software.

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.
Ethernet Port
The GRP has one Ethernet port available, using one of the following two
connection types:
•RJ-45 receptacle—An 8-pin media dependent interface (MDI) RJ-45
receptacle for either IEEE 802.3 10BASE T (10 Mbps) or IEEE 802.3u
100BASE TX (100 Mbps) Ethernet connections.
•MII receptacle—A 40-pin media independent interface (MII) receptacle that
provides additional flexibility in Ethernet connections. The pinout of this
standard 40-pin receptacle is defined by the IEEE 802.3u standard.
Note The RJ-45 and MII receptacles on the GRP 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 at
the same time.
Performance Route Processor
This section provides an overview of the PRP (Figure A-3) and its use as the main
system processor for the Cisco 12404 router.
This section provides information on the following PRP functionality.
