GRP Redundancy
When two GRPs are installed in a Cisco 12000 Series Router, one GRP is the active GRP, and the other is the backup, or standby GRP. If the active GRP fails or is removed from the system, the standby GRP detects the failure and initiates a switchover. During a switchover, the standby GRP assumes control of the router, connects with the network interfaces, and activates the local network management interface and system console.
Note
Cisco IOS Software Requirements
For software configuration information, refer to the Cisco IOS software configuration and command reference publications for the installed Cisco IOS Release. Also refer to the Cisco IOS software release notes for additional information.
The GRP line card is supported in Cisco IOS Release 11.2(9)GS and later. GRP configurations with
512 MB of route memory are only compatible with Product Number GRP-B=.

Note
SRAM
SRAM provides secondary CPU cache memory. The standard GRP configuration is 512 KB. Its principal function is to act as a staging area for routing table updates information to and from the line cards. SRAM is not user configurable or field upgradeable.
NVRAM
System configuration files, 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 5 years. NVRAM is not user configurable or field-upgradeable.
Flash Memory
Both the onboard and Flash 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 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 software boot image, and the Flash memory card or Flash disk contains the Cisco IOS software image.
System Status LEDs
The two types of system status LEDs used on the GRP.
Status LEDs
The GRP has the following eight status LEDs:
•
•
•
Display LEDs
The alphanumeric display LEDs are organized as two rows of four characters each. The display content is controlled by the MBus software of the GRP. Both rows of the display are powered by the MBus module.
These alphanumeric display LEDs provide system status messages that are displayed during the boot process and after the boot process is completed.
During the boot process, the display LEDs are controlled directly by the MBus. After the boot process, they are controlled by the Cisco IOS software (via the MBus), and display messages designated by the Cisco IOS software.
The LED displays indicate the following:
•
•
•
Soft Reset Switch
A soft reset switch provides a reset to the R5000 software on the GRP. You access the soft reset switch through a small opening in the GRP faceplate. To depress the switch, insert a pape rclip or a similar object into the opening.
Caution
Flash Card Slots
The GRP includes two Flash card slots. Either slot can support an ATA Flash disk or a linear Flash memory card.
Note
All combinations of different Flash card devices are supported by the GRP. You can use ATA Flash disks, linear Flash memory cards, or a combination of the two. Each slot has an ejector button for ejecting a card from the slot.
Note
Asynchronous Serial Ports
Two asynchronous serial ports on the GRP, the console and auxiliary ports, allow you to connect external serial devices to monitor and manage the system. The console port is an Electronic Industries Association/Telecommunications Industry Association (EIA/TIA)-232 receptacle (female) that provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.
Note
The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment (DTE) interface; the auxiliary port supports flow control and is often 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 connection types:
•
•
Note
The transmission speed of the Ethernet port is auto-sensing and is determined by the network to which the Ethernet interface is connected; it is not user configurable. 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 can be expected if you use either the MII or RJ-45 connection.

Connecting to the Console Port
The system console port on the GRP is a DCE DB-25 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in Figure 5. Before connecting the console port, check your terminal's documentation to determine the baud rate of the terminal you plan to use. The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600, 8N2). The console port requires a straight-through EIA/TIA-232 cable. Use the console cable provided to connect the terminal to the console port on the GRP.
Figure 5 Console and Auxiliary Port Connections
Note
The console port on the GRP is an EIA/TIA-232, DCE DB-25 receptacle. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The console port does not support modem control or hardware flow control. Table 2 lists the pinout for this port.
Connecting to the Auxiliary Port
The auxiliary port on the GRP is an EIA/TIA-232 DTE, DB-25 plug for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the router. The port is labeled Auxiliary. An example of a modem connection is shown in Figure 5. The asynchronous auxiliary port supports hardware flow control and modem control. Table 3 lists the pinout for this port.
Connecting to the Ethernet Port
Information you need to make connections to the Ethernet port on your GRP is presented in the following sections:
•
•
Ethernet Interface Receptacles, Cables, and Pinouts
The two Ethernet interface receptacles on the GRP are a single media independent interface (MII), 40-pin, D-shell type receptacle, and a single RJ-45 receptacle. The RJ-45 receptacle provides a media dependent interface (MDI) Ethernet port. You can use either one or the other, but not both at the same time.
Each connection supports IEEE 802.3 and IEEE 802.3u interfaces compliant with the 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet port is auto-sensing and is determined by the network to which the Ethernet interface is connected; transmission speed is not user configurable.
RJ-45 Connections
Figure 6 shows the GRP RJ-45 receptacle and cable connectors. The RJ-45 connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Table 4 lists the pinout for the RJ-45 receptacle.

Figure 7 Straight-Through Cable Pinout (Connecting MDI Ethernet Port to MDI-X Wiring)
Figure 8 Crossover Cable Pinout (for Connecting Two GRPs)
MII Connections
The MII connection requires an external physical sublayer (PHY) and an external transceiver. Depending on the type of media you use between the MII connection on the GRP and your switch or hub, the network side of your 100BASE-T transceiver should be appropriately equipped—with SC-type or ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 9 shows the pin orientation of the female MII receptacle on GRP.
The MII receptacle uses two screw-type locks, called jackscrews (see Figure 9), to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews (screws that you can tighten with your fingers) that you fasten to the jackscrews on the GRP's MII connector. Use the jackscrews to provide strain relief for your MII cable. (The RJ-45 modular plug has strain relief functionality incorporated into the design of its standard plastic connector.)

Ethernet Interface Cable Connection Procedure
The RJ-45 and MII receptacles on the GRP represent two physical connection options for one Ethernet interface; therefore, you can use either the RJ-45 connection or the MII connection, but not both simultaneously. RJ-45 and MII cables are not available from Cisco Systems; they are available from outside commercial cable vendors.
Use the following procedure to connect cables to the GRP's Ethernet interface:
•
•
The Ethernet interface on the GRP is an end station device, not a repeater; therefore, you must connect the Ethernet interface to a repeater or hub.
Figure 10 Connecting MII or RJ-45 Cables to GRP (Vertical Orientation)
Caution
Caution
Figure 11 shows an example of the functionality of the Ethernet port. In this example, you cannot access Network 2.0.0.0 via the Ethernet port (E0) on the GRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 11.)
To access Network 2.0.0.0 from Router A, you must use an interface port on one of your line cards (in this example, a Packet-over-SONET (POS) line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 11.)
