GRP, PRP, and Line Card Memory Overview
This section provides an overview of the memory systems on the GRP, PRP, and Cisco 12000 Series Internet Router line cards.
GRP Memory
The GRP uses the following types of memory (see Figure 1 for memory locations):
•Route memory—Dynamic random access memory (DRAM) enables an onboard processor to run Cisco IOS software and store network routing tables. You can configure route memory from the factory default of 128 MB to the maximum configuration of 512 MB.
Note GRP route memory configurations of 512 MB are only compatible with Product Number GRP-B=. Cisco IOS Release 12.0(19)S or 12.0(19)ST or later, and ROMMON Release 11.2 (181) or later, are also required.
•GRP Flash memory—Single in-line memory module (SIMM) stores the boot helper software that enables you to boot the router when a valid Cisco IOS software image is not available on a Flash memory card.
•GRP linear Flash memory card—A convenient, offline medium for storing a copy of the default Cisco IOS software image. This card can be inserted into either of the two Flash memory slots on the GRP, so that you can load router software into GRP main memory.
•GRP erasable programmable read-only memory (EPROM)—Contains a ROM monitor that enables you to boot the default Cisco IOS software image from a Flash memory card if the Flash memory SIMM does not contain a boot helper image.
•GRP Random access memory—Nonvolatile random-access memory (NVRAM) provides a stable medium for storing the router's configuration files, the environmental monitoring logs, and the contents of the router's virtual configuration register.
PRP Memory
The PRP uses the following types of memory. (See Figure 2 for memory locations):
•Route memory—Synchronous dynamic random access memory (SDRAM) enables an onboard processor to run Cisco IOS software and store network routing tables. You can configure route memory from the factory default of 512 MB to the maximum configuration of 2 GB.
•PRP onboard Flash memory—Single in-line memory module (SIMM) stores the boot helper software to boot the router when a valid Cisco IOS software image is not available on a Flash disk or a linear Flash memory card.
•PRP Flash disk—A convenient, offline medium for storing a copy of the default Cisco IOS software image. The Flash disk can be inserted into either of the two Flash disk slots in the PRP, so that you can load router software into PRP main memory.
•PRP erasable programmable read-only memory (EPROM)—Contains a ROM monitor that enables you to boot the default Cisco IOS software image from a Flash disk if the Flash memory SIMM does not contain a boot helper image.
•PRP Random access memory—Nonvolatile random-access memory (NVRAM) provides a stable medium for storing the router's configuration files, the environmental monitoring logs, and the contents of the router's virtual configuration register.
Line Card Memory
Cisco 12000 Series Router line cards use the following types of memory:
•Route memory—Dynamic random access memory (DRAM) or small outline DIMM (SODIMM) memory enables an onboard processor to run Cisco IOS software and store network routing tables.
•Packet memory—Synchronous dynamic random access memory (SDRAM) is arranged in banks of SDRAM (see Figure 3 and Figure 4) and consists of a set of receive (RX) and transmit (TX) buffers that help to manage the flow of packet data into and out of the line card.
Memory Considerations
Consider the following to ensure proper memory configurations:
•Packet memory options and functions apply only to line cards. There is no packet memory on the GRP and PRP. Different line cards support different default and maximum packet memory configurations. Line card memory configurations are determined by their engine type. See Table 6 for more information.
•Of the various types of memory used on the GRP, PRP, and line cards, only two types of memory are field serviceable (that is, memory that can be replaced in the field): DRAM and SDRAM route memory (GRP, PRP, and line cards) and SDRAM packet memory (certain line cards only).
GRP Route Memory
The processor on the GRP uses onboard DRAM to perform several tasks for Cisco 12000 Series
Internet Routers, including the following:
•Running the Cisco IOS software image
•Storing and maintaining the network routing tables
•Loading the Cisco IOS software image into installed line cards
•Formatting and distributing updated routing tables to installed line cards
•Monitoring temperature and voltage alarm conditions of installed cards and shutting them down when necessary
•Supporting a console port that enables you to configure the router using an attached terminal
•Participating in network routing protocols (together with other routers in the networking environment) to update the router's internal routing tables
Figure 1 shows the locations of the processor memory DRAM DIMM sockets and the Flash memory SIMM socket on the GRP.
The two route memory DIMM sockets on the GRP, labeled U39 (route memory bank 1) and U42 (route memory bank 2), respectively, enable you to configure route memory in desired increments ranging from 128 to 512 MB.
Note GRP route memory configurations of 512 MB are only compatible with Product Number GRP-B=. Cisco IOS Release 12.0(19)S or 12.0(19)ST or later and ROMMON Release 11.2 (181) or later are also required.
Table 1 lists the available route memory configurations and associated product numbers for the GRP. The default route memory configuration is 128 MB. If the GRP is currently equipped with one 64-MB DIMM in socket U39, you can upgrade memory by installing a second 64-MB DIMM in socket U42, or by removing the existing 64-MB DIMM and replacing it with one 128-MB DIMM.

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 Performance Route Processor (PRP) in the same chassis. Refer to the Route Processor Redundancy Plus for the Cisco 12000 Series Router publication for more information.
PRP Route Memory
The processor on the PRP uses onboard SDRAM to perform several tasks for Cisco 12000 Series
Internet Routers, including the following:
•Running the Cisco IOS software image
•Storing and maintaining the network routing tables
•Loading the Cisco IOS software image into installed line cards
•Formatting and distributing updated routing tables to installed line cards

Note If your system includes redundant PRPs, both PRPs 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 configuring your router using mixed route processor cards. Refer to the Route Processor Redundancy Plus for the Cisco 12000 Series Router publication for more redundancy information.
Line Card Memory
There are two types of user-configurable line card memory on most line cards:
•Route or processor memory
•Packet memory
Line card memory configurations and memory socket locations differ, depending on the type of line card. In general, all line cards share a common set of memory configuration options for route memory, but support packet memory differently. For clarity in describing how to remove and install memory in this publication, line cards fall into the following groups, based on certain physical characteristics:
•Engine 0 and Engine 1 line cards (See Figure 3.)
•Engine 2 line cards (See Figure 4.)
•Internet Service Engine (ISE), formerly known as Engine 3 line cards (See Figure 5.)
•Engine 4 and Engine 4+ line cards (See Figure 6.)
Note The procedures for replacing memory on both the Engine 4 and the Engine 4+ line cards is identical.
The general characteristics that determine which engine type a line card belongs to are as follows:
•Location of memory module sockets on the line card
•Number and function of memory module sockets
•Type of memory module sockets
Engine 0 and Engine 1 Line Card Memory Locations
Figure 3 shows the dual in-line memory module (DIMM) socket locations on an Engine 0 or Engine 1 line card. This line card is equipped with six DIMM sockets:
•Two route memory DIMM sockets
•Two pairs of packet memory DIMM sockets (RX and TX pairs)

Line Card Packet Memory
Line card packet memory temporarily stores data packets awaiting switching decisions by the line card processor. Once the line card processor makes the switching decisions, the packets are propagated into the router's switch fabric for transmission to the appropriate line card.
•Engine 0 and Engine 1 line cards (see Figure 3) include four SDRAM DIMM sockets for packet memory, paired as follows:
–Receive (RX) buffer—Two SDRAM DIMM sockets labeled RX DIMM0 and RX DIMM1
–Transmit (TX) buffer—Two SDRAM DIMM sockets labeled TX DIMM0 and TX DIMM1
•Engine 2 line cards (see Figure 4) include four SDRAM DIMM sockets for packet memory, paired as follows:
–Transmit (TX) buffer—Two SDRAM DIMM sockets labeled TX DIMM0 and TX DIMM1
–Receive (RX) buffer—Two SDRAM DIMM sockets labeled RX DIMM0 and RX DIMM1
•ISE line cards (see Figure 5) include four SODIMM sockets for packet memory. This memory is not field serviceable.
•Engine 4 and Engine 4+ line cards (see Figure 6) include two DDR DIMM sockets for packet memory. This memory is not field serviceable.
Note For a line card to operate, both receive packet memory DIMM sockets and both transmit packet memory DIMM sockets must be populated. The SDRAM DIMMs installed in a given buffer (either receive or transmit) must be the same type and size, but receive and transmit buffers can operate with different memory sizes.
Table 5 lists the available packet memory configuration options for Cisco 12000 Series Router line cards. Cisco packet memory configuration options consist of four DIMMs of the same type and size (two DIMMs for the RX socket pair and two DIMMs for the TX socket pair). The actual default and maximum packet memory configuration options depend on the type of line card. Table 6 lists engine types for each available Cisco 12000 Series Router line card.

Preparing for Installation
Installation preparation is presented in the following sections:
•Safety Guidelines
•Preventing Electrostatic Discharge
•Required Tools and Equipment
Safety Guidelines
Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.
The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.
Note Review the safety warnings listed in the Regulatory Compliance and Safety Information for
Cisco 12000 Series Internet Routers publication (Document Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining a line card or its components.
•Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to enter into any components.
•Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with line cards or components.
•Cisco equipment operates safely when it is used in accordance with its specifications and product usage instructions.
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 line card. Cisco recommends using an ESD-preventive strap whenever you are handling network equipment or one of its components.
The 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 chassis.
•Handle line cards by the captive installation screws, the provided handle, ejector levers, or the line card metal carrier only; avoid touching the board or connector pins.
•Place a removed line card 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 line card and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Required Tools and Equipment
You will need the following tools and parts to install or replace memory on the Cisco 12000 Series Router GRP, PRP, or line cards:
•Flat-blade or Number 2 Phillips screwdriver.
Some early models of the GRP and line cards are equipped with slotted-head captive screws that fasten the card in the card cage. Later models of the GRP, PRP, and line cards are equipped with combination-head captive screws, which can take either a flat-bladed screwdriver or a Phillips screwdriver.
•Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares for the Cisco 12000 Series Routers.
•Antistatic mat or surface.
•The DIMM modules for configuring the GRP, PRP, or line card memory (for the GRP, see Table 1; for the PRP see Table 2; for line cards, see Table 4 and Table 6).
Replacing and Upgrading Route Processor Route Memory
This section describes how to replace or upgrade the route memory DRAM DIMMs on the GRP and the SDRAM DIMMs on the PRP. Unless otherwise stated, throughout the remainder of this publication the GRP and the PRP are called an RP.
Note If the router is equipped with a single RP, you must power down the router before removing the RP to replace or upgrade processor memory DIMMs on the RP. If the router is equipped with an optional, redundant RP, you can remove one of the RPs while the router is running without affecting router operation. Redundant RPs should both have the same memory size.
This section contains the following procedures:
•Removing Route Memory DIMMs from an RP
•Installing Route Memory DIMMs on an RP
•Checking the Installation of RP Memory
If you are upgrading memory by adding a matching DIMM to an existing single-DIMM configuration, use the procedure in the "Installing Route Memory DIMMs on an RP" section.
If you are replacing a defective DIMM or performing a memory upgrade that requires the existing DIMMs to be removed, you must first remove the existing DIMMs. In that case, use the procedure in the "Removing Route Memory DIMMs from an RP" section. After you have removed the DIMM from the RP, proceed to the "Installing Route Memory DIMMs on an RP" section.
Removing Route Memory DIMMs from an RP
Review the following route memory removal scenarios:
•If you are upgrading the memory by adding a matching DIMM to an existing single-DIMM configuration (only socket U39 occupied), use the procedure in the "Installing Route Memory DIMMs on an RP" section. For example, if you want to upgrade memory from 64 MB to 128 MB (two 64-MB DIMMs) or from 128 MB to 256 MB (two 128-MB DIMMs), you can install the appropriate DIMM in socket U42.
•If you are replacing a defective DIMM or performing a memory upgrade that requires the existing DIMMs to be removed, use the following procedure. For example, if you want to upgrade memory from 64 MB to 128 MB (one 128-MB DIMM) or 256 MB (two 128-MB DIMMs), you must remove the existing DIMM before installing the new DIMMs.
Note After removing processor memory DIMMs from the RP, place them in an antistatic bag for ESD protection. Removed route memory DIMMs can be used in other compatible equipment.
To remove a DIMM from an RP, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Position the RP on the antistatic mat so that the faceplate is toward you and the backplane connector is away from you.
Step 3 Locate the route memory DIMMs on the RP. (See Figure 1.) The DIMMs occupy U39 (bank 1) and U42 (bank 2).
Step 4 For the DIMM you want to remove, pull down the lever on the DIMM socket to release the DIMM from the socket. (See Figure 7.)
Figure 7 Using the DIMM Socket's Release Lever to Remove DIMMs
Caution Handle the edges of the DIMM only. (See
Figure 8.) Do not touch the integrated circuit devices on the DIMM, the metal traces, or
fingers, along the edge of the DIMM, or the pins in the DIMM socket.
Step 5 When one end of the DIMM is released from the socket, grasp each end of the DIMM with your thumb and forefinger and pull the DIMM completely out of the socket.
Figure 8 Handling a DIMM
Step 6 Place the DIMM in an antistatic bag to protect it from ESD damage.
Repeat Step 4 through Step 6 for the remaining DIMM, if required for your upgrade.
Installing Route Memory DIMMs on an RP
This section describes how to install a new DIMM on the RP.
Caution To prevent router and memory problems when installing memory, the card's DIMMs must be 3.3-volt, 60-ns, extended data output (EDO) devices. Do not attempt to install other devices in the RP's DIMM sockets.
Caution DIMMs are sensitive electronic components that can be damaged by ESD and contaminated by mishandling. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket.
To install the new DIMMs, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Place the RP on an antistatic mat or pad and position the RP so that the faceplate is toward you and the backplane connector is away from you.
Step 3 Locate the two DIMM sockets on the RP, labeled as follows (see Figure 1 and Figure 2):
•U39 (bank 1) GRP
•U42 (bank 2) GRP
•U15 (bank1) PRP
•U18 (bank2) PRP
Step 4 Remove a new DIMM from the antistatic bag.
Step 5 Hold the DIMM component-side-up, with the connector edge (the metal fingers) closest to you. Hold the ends of the DIMM between your thumb and forefinger. (See Figure 8.)
Step 6 Tilt the DIMM to the same angle as the socket and insert the entire connector edge into the socket. The two notches (keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in the socket.
Caution When inserting DIMMs, use firm but not excessive pressure. If you damage a socket, you will have to return the RP to the factory for repair.
Step 7 Gently push the DIMM into the socket until the lever is flush against the side of the DIMM socket and the DIMM's edge connector is fully inserted. (See Figure 9.) If necessary, rock the DIMM gently back and forth to seat it properly.
Figure 9 Installing a DIMM in a DIMM Socket
Step 8 Check that the release lever is flush against the side of the DIMM socket. If it is not, the DIMM might not be seated properly. If the DIMM appears to be misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until the release lever is flush against the side of the DIMM socket.
Step 9 Repeat Step 4 through Step 8 to install the remaining DIMM, as required.
Proceed to the next section and follow the procedure to replace the RP in the card cage slot from which you removed it. If the router is equipped with a single RP, you will need to restart the router before you can perform an installation check. If the router is equipped with an optional, redundant RP, the RP you return to the card cage will power up and reinitialize when it is seated in the backplane connector.
Checking the Installation of RP Memory
Turn on power and allow the router to reboot. The time required for the router to initialize varies with different router and memory configurations. Routers with 256 MB or more of memory might take longer to boot than those with less. If the router fails to boot properly or if the console terminal displays a checksum or memory error after you have installed new DIMMs, check the following:
•Ensure that all DIMMs are installed correctly. If necessary, shut down the router and remove the RP. To check the DIMMs, look straight down on the DIMMs to inspect them at eye level. They should all be aligned at the same angle and the same height when properly installed. If a DIMM appears to stick out or rest in the socket at a different angle from the others, remove the DIMM and reinsert it. Then replace the RP in the card cage and reboot the router for another installation check.
•DIMMs must be EDO, 3.3-volt, 60-ns DRAM (GRP) or PC-133-compliant SDRAM (PRP) devices. The speed is printed along one edge of the DIMM.
If the router fails to restart properly after several attempts, access Cisco.com or contact a Cisco customer service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve the problem.
Removing and Installing Line Card Memory
Cisco 12000 Series Router line cards use the following types of field serviceable memory:
•Route memory (DRAM)—Each Cisco 12000 Series Router line card includes DRAM DIMM or SODIMM sockets. (See Figure 3, Figure 4, Figure 5, and Figure 6.) The DRAM is used by the line card's processor. (See Table 4 for all route memory options.)
•Packet memory (SDRAM)—Each Cisco 12000 Series Router line card includes SDRAM DIMM or SODIMM sockets. (See Figure 3, Figure 4, Figure 5, and Figure 6.) The SDRAM is used by the line card's transmit (TX) and receive (RX) buffers. See Table 5 for the default packet memory configuration of each line card.
Maximum configurations also depend on the line card type. Some line cards support a maximum configuration of 128 MB, while other line cards support a maximum configuration of 512 MB.
Caution Packet memory on ISE, Engine 4, and Engine 4+ line cards is not field serviceable. On ISE line cards, the packet memory SODIMM modules look identical to the route memory SODIMMs; however, they will
not work in the packet memory sockets. Do not attempt to install route memory SODIMM modules in packet memory sockets; this will cause the board to fail when you reboot the card.
Both route memory and packet memory can be replaced or upgraded in the field. See Table 4 for the available DRAM DIMM options or Table 5 for the available SDRAM DIMM options that you can use for configuring memory. Observe the following guidelines:
•Line card route memory DRAM (Engine 0, 1, and 2)
–Route memory DIMM0 socket must always be populated.
–For certain memory configurations, the route memory DIMM1 socket can remain empty.
–DRAM DIMMs must be 3.3V devices.
•Line card route memory DRAM (ISE, Engine 4, and Engine 4+)
–ISE line cards—Use two 256-MB, 144-pin SODIMM memory modules
–ATM ISE line cards—Can also use one or two 512-MB, 144-pin SODIMM memory modules
–Engine 4 and Engine 4+ line cards—Use one 256-MB, 144-pin SODIMM memory module
•Line card transmit and receive packet memory SDRAM (Engine 0, 1, and 2)
–All four DIMM sockets for SDRAM buffer memory must be populated.
–Both DIMM sockets for a given buffer pair (either those for the transmit buffer or those for the receive buffer) must be populated with SDRAM DIMMs of the same type and size.
–Size of the SDRAM DIMMs in the transmit buffer need not match the size of the SDRAM DIMMs in the receive buffer.
–SDRAM DIMMs must be 3.3V devices.
Caution ISE, Engine 4, and Engine 4+ line card packet memory is not field serviceable. Only qualified Cisco personnel should service these memory modules.
Caution On ATM ISE line cards, only the route memory in DIMM1 is user replaceable. You must use the same size memory in DIMM1 as installed in DIMM0. The memory module in DIMM0 can only be replaced by the Cisco Technical Assistance Center (TAC).
This section contains the following procedures:
•Removing a Line Card from the Router
•Removing a DIMM from a Line Card
•Installing a DIMM in a Line Card
•Removing a SODIMM
•Installing a SODIMM
•Checking the Installation of Route Memory
Removing a Line Card from the Router
For information on removing and installing a line card, refer to the installation and configuration note for the line card in use, in addition to the installation and configuration guide for the router in use.
Removing a DIMM from a Line Card
Engine 0, 1, and 2 line cards use DRAM DIMMs for route memory and SDRAM DIMMs for the transmit and receive buffer packet memory. The locations of the DIMM sockets for these two types of line card memory are shown in Figure 3 and Figure 4.
Caution ISE, Engine 4, and Engine 4+ line card packet memory is not field serviceable. Only qualified Cisco personnel should service these memory modules. See the
"Removing a SODIMM" section
To remove a DIMM from a line card, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and connect the leash to one of the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis.
Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.
Step 3 Locate the DIMM sockets on the line card. (See Figure 3 and Figure 4.)
Note Some line cards use DIMM sockets equipped with a single release lever, as shown in Figure 7; other line cards use DIMM sockets equipped with dual release levers, as shown in Figure 10. Both DIMM sockets operate in the same general way.
Figure 10 DIMM Socket with Dual Release Levers
Step 4 For the DIMM you want to remove, use the socket release levers to eject the DIMM.
