Router Information
For hardware installation and maintenance information on Cisco 12000 Series Routers, refer to the installation and configuration guide for your router. This includes information on card slot locations and other general requirements.
Supported Platforms
The GRP operates on all Cisco 12000 series Internet Routers with the following requirements:
•Cisco 12016 and Cisco 12416—GRP plugs into slot 7 in the upper card cage. If the router is equipped with an optional, redundant GRP, it must be installed in the far left slot of the lower card cage (slot 8).
•Cisco 12410—GRP plugs into slot 9. If the router is equipped with an optional, redundant GRP, it must be installed in slot 8.
•Cisco 12406—GRP plugs into any slot; however, slot 5 is recommended. If the router is equipped with an optional, redundant GRP, it can be installed in any of the remaining five slots.
•Cisco 12404—GRP plugs into any of the five slots in the card cage, but slot 0 (zero) is the recommended slot for the first GRP. If the router is equipped with an optional, redundant GRP, it can be installed in any of the remaining slots.
•Cisco 12012—GRP plugs into slot 0 in the upper card cage. In a dual GRP system, the second GRP is located in slot 11. This is the default factory configuration and is recommended to avoid heatrelated problems. The far right slot labeled Alarm card is reserved for the alarm card.
•Cisco 12008—GRP plugs into any slot in the upper card cage in the Cisco 12008 except the middle two slots (which are reserved for the CSC cards and labeled CSC 0 and CSC 1).
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 If your system includes redundant GRPs, both GRPs should have the same memory size. Redundancy is not supported when using a GRP and a PRP in the same chassis. Cisco strongly recommends that you avoid using mixed route processor cards to configure your router. Refer to the Route Processor Redundancy Plus for the Cisco 12000 Series Internet Router publication for more information on redundancy.

Product Overview
Caution To prevent memory problems, DRAM DIMMs must be +3.3VDC, 60-nanosecond (ns) EDO devices. Do not attempt to install other devices in the DIMM sockets. Cisco recommends that you use Cisco-approved memory options. (See Table 14 on page 49.)
The following DRAM upgrade kits for the GRP and line cards are listed by product number:
•64-MB DRAM upgrade kit (one 64-MB DIMM)—MEM-GRP/LC-64=
•128-MB DRAM upgrade kit (one 128-MB DIMM)—MEM-GRP/LC-128=
•256-MB DRAM upgrade kit (two 128-MB DIMMs)—MEM-GRP/LC-256=
The following DRAM upgrade kits for Product Number GRP-B= are available (listed by product number):
•256-MB DRAM upgrade kit (one 256-MB DIMM)—MEM-GRP-256=
•512-MB DRAM upgrade kit (two 256-MB DIMMs)—MEM-GRP-512-UPG=
These kits are available only for Product Number GRP-B=. They are not compatible with any other Cisco product. See Table 14 for all requirements related to the 512-MB memory upgrade.
Note MEM-GRP/LC-64= can be used to replace bank 1 or bank 2 in the 128-MB default configuration on the GRP line card. Cisco does not recommend using a 64-MB configuration on this card.
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.

Product Overview
System Status LEDs
The two types of system status LEDs used on the GRP.
•Status LEDs
•Display LEDs
Status LEDs
The GRP has the following eight status LEDs:
•2 PCMCIA activity LEDs (one LED per PCMCIA slot)—Each LED goes on when its PCMCIA slot is accessed. The LEDs receive power from the switched slot voltage.
•4 RJ-45 Ethernet port LEDs—These LEDs are used in conjunction with the RJ-45 Ethernet connector. When the MII Ethernet port is in use, the LEDs are disabled. The LEDs indicate link activity (LINK), collision detection (COLL), data transmission (TX), and data reception (RX).
•2 RJ-45 or MII Ethernet port selection LEDs—These two LEDs, when on, identify which 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.
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:
•Status of the GRP
•System error messages
•User-defined status/error messages
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 To prevent system problems or loss of data, use the soft reset switch only on the advice of Cisco service personnel.

Product Overview
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 The GRP only supports +5VDC Flash card devices. It does not support +3.3VDC Flash card devices.
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 Linear Flash memory cards may not have the capacity to meet the requirements of your configuration. However, they can be used for emergency file recovery applications.
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 EIA/TIA-232 was formerly RS-232.
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:
•RJ-45 receptacle—8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections.
•MII receptacle—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 RJ-45 connection or the MII connection, but not both simultaneously.
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.

Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral component of the GRP. Cisco recommends using a ESD-preventive strap whenever you are handling a router or one of its components.
Following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Connect the equipment end of the connection cord to an ESD connection socket on the router or to bare metal on the router chassis.
•Handle the GRP by the card carrier and by the left-side spring-loaded screw (horizontal view). Avoid touching board components or connector pins.
•Place a removed GRP board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.
•Avoid contact between the GRP and clothing or jewelry. The wrist strap protects the board only from ESD voltages on the body; ESD voltages on clothing or jewelry can still cause damage.
Working with Electrical Equipment
Follow these basic guidelines when working with any electrical equipment:
•Before beginning any procedure requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
•Disconnect all power and external cables before moving a chassis.
•Do not work alone when potentially hazardous conditions exist; never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Replacing a GRP
Required Tools and Parts
You need the following tools and parts to remove and replace a GRP. If you need additional equipment, contact a Cisco customer service representative for ordering information.
•3/16-inch flat-blade screwdriver for the captive installation screws that secure the GRP in its slot.
•ESD-prevention equipment or the disposable ESD-preventive wrist strap included with all spares and upgrade kits.
•Antistatic mat, foam pad, or bag for the removed GRP. Place the removed GRP into an antistatic bag if you plan to return it to the factory, or on an antistatic mat or foam if you are replacing components and will reinstall the GRP.
Replacing a GRP
The following sections describe the procedures for replacing a GRP in your system.
Before beginning the procedures, verify that your system meets the minimum requirements as described in the “Preparing for Installation” section on page 10.
When your system meets minimum requirements, proceed to the “Removing a GRP” section on page 14 for instructions on removing the GRP, and then to the “Installing a GRP” section on page 17 for reinstallation instructions.
Caution We recommend that you do not remove a GRP while the system is operating. Removing the installed GRP from a system while the system is operating will cause the system to stop forwarding packets and might cause the system to cease network operation.
Removing a GRP
When you remove a GRP from a slot, be sure to use the ejector levers, which help to ensure that the GRP is fully dislodged from the backplane connector. (See Figure 3.)

Caution A GRP that is only partially removed from the backplane can halt the system.
Caution Before you replace the GRP, back up the running configuration to a Trivial File Transfer Protocol (TFTP) file server or an installed Flash memory card or Flash disk so that you can retrieve it later. If the configuration is not saved, the entire configuration will be lost inside the NVRAM on the removed GRP, and you will have to reenter the entire configuration manually. For instructions on how to save the configuration file, see the “Copying Files to Flash Memory” section on page 41. This procedure is not necessary if you are temporarily removing a GRP; lithium batteries will retain the configuration in memory until you replace the GRP in the system.

To remove a GRP, follow these steps:
Step 1 Turn off system power.
Step 2 If you are replacing the GRP in a system with one GRP, copy the currently running configuration file to a TFTP server or Flash memory so that you can retrieve it later. (See the “Copying Files to Flash Memory” section on page 41.)
Step 3 Attach an ESD-preventitive wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage (Cisco 12012, Cisco 12016, or Cisco 12416); to the ESD connection socket located on the lower left edge of the upper card cage (Cisco 12008); or to bare metal on the frame.
If you are replacing a GRP, disconnect any devices that are attached to the console or auxiliary ports. If you are removing a GRP for maintenance and will reinstall the same one, you can leave the devices attached, provided that doing so will not strain the cables.
Step 4 Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the ends of the GRP. (See Figure 4a.)
Step 5 Place your thumbs on the ends of each of the ejector levers and simultaneously pull them both away from the GRP faceplate (in the direction shown in Figure 4b) to release the GRP from the upper card cage slot and to dislodge the GRP edge connector from the backplane.
Step 6 Grasp the GRP faceplate with one hand and pull the GRP straight out of the slot, keeping your other hand under the GRP to guide it. (See Figure 4.) Keep the GRP edge connector parallel to the backplane.
Caution Avoid touching the GRP printed circuit board, components, or any edge connector pins.

Replacing a GRP
Step 7 Place the removed GRP on an antistatic mat or foam. If you plan to return the GRP to the factory, immediately place it in an antistatic bag to prevent ESD damage.
Installing a GRP
When you install a GRP, be sure to use the ejector levers, which help to ensure that the GRP is fully inserted in the backplane connector. (See Figure 3.) When you simultaneously push the ejector levers inward (toward the center of the GRP), the ejector levers push the GRP into the slot and ensure that the GRP backplane connector is fully seated in the backplane.
Caution A GRP that is only partially connected to the backplane can halt the system.
Use the following procedure to install a GRP:
Step 1 Use an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Grasp the GRP faceplate with one hand and place your other hand under the carrier to support and guide it into an upper card cage slot. (See Figure 4.)
Caution Avoid touching the GRP printed circuit board, components, or any edge connector pins.
Step 3 Place the bus-connector edge of the GRP in the appropriate slot and align the notches along the edge of the carrier with the grooves at the top and bottom of the slot.
Step 4 While keeping the GRP edge connector parallel to the backplane, carefully slide the carrier into the slot until the GRP faceplate makes contact with the ejector levers, then stop.
Step 5 Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously push both ejectors toward the center of the GRP faceplate until they are perpendicular to the GRP faceplate. (See Figure 4a.)
Step 6 Using a 3/16-inch flat-blade screwdriver, tighten the captive screws on the ends of the GRP. The captive screws prevent the GRP from becoming partially dislodged from the backplane and ensure proper EMI shielding. (These captive screws must be tightened to meet EMI specifications.)
Step 7 If you disconnected the console terminal to remove the GRP, or if you are installing a new GRP, connect the console terminal to the console port. (See the “Connecting to the Console Port” section on page 18.)
Step 8 Ensure that the console terminal is turned on.
Step 9 Turn on system power.
Step 10 Attach the network end of your RJ-45 or MII cable to your transceiver, switch, hub, repeater, DTE, or other external equipment. Be sure to use the appropriate strain relief on cable connections.
