Chapter 5 Installing Memory in the Router

DRAM SIMMs (Used in Cisco 3620 and Cisco 3640 Routers)

This section describes how to upgrade DRAM single in-line memory modules (SIMMs) in Cisco 3620 and Cisco 3640 routers. You might need to upgrade the DRAM SIMMs for the following reasons:

• You upgraded the Cisco IOS feature set or release and it requires additional DRAM.

• The router maintains large routing tables or other memory-intensive features, such as spoofing or

protocol translations.

The Cisco 3620 and Cisco 3640 routers each contain four 72-pin SIMM sockets (or banks) for DRAM. Each socket can be filled with a single 32-bit-wide, 72-pin DRAM SIMM. You can configure DRAM as a mixture of primary or main memory, which is reserved for the CPU, and shared memory, which is used for data transmitted or received by modules and WAN interface cards.

To see how much memory is currently installed in the router, enter the show version command while the router is in the privileged EXEC mode (Router# prompt). Near the middle of the resulting output, a message similar to the following displays:

Cisco 3640(R4700) processor (revision 0x00) with 24576K/8192K bytes of memory.

This line shows how much memory is installed (in this example, 24576K/8192K). The first number represents primary memory and the second number represents shared memory.

You can configure DRAM to be either 32 or 64 bits wide. To use 64-bit mode, you must install DRAM SIMMs in pairs of the same size. Generally, basic software feature sets (such as IP) use 32-bit DRAM SIMMs and robust software feature sets (such as Enterprise) use 64-bit DRAM SIMMs.

Replacing DRAM and SDRAM

Note In the Cisco 3620 router, DRAM supports 32-bit operation only, whereas in the Cisco 3640 router,

DRAM supports either 32- or 64-bit operation.

Note In 32-bit mode, the router performs approximately 20 percent slowerthan when DRAM is configured

for 64-bit mode operation.

Each SIMM socket corresponds to one bank of memory. Fill banks consecutively with no gaps; start fillingbanks from 0, and empty banks starting with 3. Bank 0 must always be filled first and emptied last.

Only certain combinations of DRAM SIMMs are permitted. These combinations are shown inTable 5-1 for 32-bit configurations used in Cisco 3620 routers, Table 5-2 for 32-bit configurations used in Cisco 3640 routers, and Table 5-3 for 64-bit configurations used in Cisco 3640 routers.

Follow these rules to use 64-bit mode DRAM configuration:

• SIMMs in banks 0 and 1 must be the same size (in MB) and have the same access time (in

nanoseconds).

• SIMMs in banks 2 and 3 must also be the same size and have the same access time.

• SIMMs in banks 2 and 3 must be less than or equal to the size of the SIMMs in banks 0 and 1.

Figure 5-5 or Figure 5-6 shows the DRAM SIMM locations in your router.

Perform this procedure to remove DRAM SIMMs:

Step 1 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the

equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the connectors.

Step 2 On the mainboard, locate the DRAM SIMM sockets shown in Figure 5-5 or Figure 5-6.

Caution Handle SIMMs by the non-connector edges only. SIMMs are ESD-sensitive components and can be

damaged by mishandling.

Step 3 Remove one SIMM at a time, beginning with the SIMM in bank 3. To lift the SIMM out of its socket,

pull the locking spring clips on both sides outward and tilt the SIMM toward the right side of the chassis, until it is free of the clips. (See Figure 5-8.)

SDRAM DIMMs Used in the Cisco 3631 and Cisco 3660 Router

This section describes how to upgrade synchronous dynamic random access memory (SDRAM) dual in-line memory modules (DIMMs) in the Cisco 3631and Cisco 3660routers. You might need to upgrade the SDRAM DIMMs for the following reasons:

• You upgraded the Cisco IOS feature set or release and it requires additional SDRAM.

• The router maintains large routing tables or other memory-intensive features, such as spoofing or

protocol translations.

The Cisco 3631 and Cisco 3660 routers contain two 168-pin DIMM sockets for SDRAM. Each socket can be filled with a single 64-bit-wide, 168-pin SDRAM DIMM. You can configure SDRAM as a mixture main memory, which is reserved for the CPU, and shared memory, which is used for data transmitted or received by modules and WAN interface cards. See Figure 5-10 and Figure 5-11 for DIMM locations.

Cisco 3660(R527x) processor (revision 0x00) with 24576K/8192K bytes of memory.

This line shows how much memory is installed (in this example, 24576K/8192K). The first number represents primary memory and the second number represents shared memory. Your router supports up to 256 MB of SDRAM.

Each DIMM socket corresponds to one bank of memory. Fill banks from 0, and empty banks starting with 1. Bank 0 must always be filled first and emptied last.

The Cisco 3631 router supports both parity and non-parity PC-100 DIMMs ranging in capacity from 64 MB to 128 MB. Only certain combinations of SDRAM DIMMs are permitted. (See Table 5-5.)

The Cisco 3660 router supports both parity and non-parity PC-100 DIMMs ranging in capacity from 16 MB to 128 MB. Only certain combinations of SDRAM DIMMs are permitted. (See Table 5-5.)

Note An advantage of parity DIMMs over non-parity DIMMs is easier identification of memory errors; a

disadvantage is lower processing speed.

Note To use a 64-bit mode SDRAM configuration, the DIMM in bank 1 must be less than or equal to the

size of the DIMM in bank 0.

Caution It is normal to feel some resistance when installing a DIMM, but do not use excessive force on the

DIMM, and do not touch the surface components.

Step 6 Repeat Step 3 through Step 5 for each DIMM.

When you finish replacing DIMMs, and have installed all internal components, proceed to the

“Replacing the Cisco 3660 Mainboard Tray” section on page 5-33.

Replacing Flash Memory SIMMs

This section describes how to upgrade the Flash memory SIMMs. The system code (Cisco IOS software) is stored in the Flash memory SIMMs. You might need to replace or add Flash memory SIMMs to upgrade to a new Cisco IOS software feature set.

The router contains one or two 80-pin Flash memory SIMMs. You can upgrade Flash memory by replacing the existing 4-MB SIMM with an 8- or 16-MB SIMM, or by adding a SIMM to the second Flash memory socket. You can install from 4 to 32 MB of Flash memory. The size of the SIMMs in the two Flash memory sockets need not be the same.

Note Flash memory SIMMs are not interchangeable with DRAM SIMMs (used in Cisco 3620 and

Cisco 3640 routers) or SDRAM DIMMs (used in Cisco 3631 and Cisco 3660 routers).

OL-2056-02

Each Flash memory SIMM socket corresponds to one bank of memory. Fill banks starting with 0, and empty banks starting with 1. Bank 0 must always be filled first and emptied last.

Booting from a Flash Memory Card

You can configurethe router to boot from a Cisco IOS image on the Flash memory card, rather than from system Flash memory. The router boots the image on the Flash memory card, copies the image to onboard DRAM, and then executes the image from DRAM. The router does not execute the image directly from the Flash memory card.

Follow these steps to specify the image on the Flash memory card as the boot image:

Step 1 Enter privileged EXEC mode:

Router> enable Password: password

Step 2 Enter global configuration mode:

Router# configure terminal

Chapter 5 Installing Memory in the Router

Step 3 Enter the boot system flash {slot0: | slot1:}[partition:filename] command to specify the boot image

location and name. In the following example, the boot image is located on the Flash memory card in the 0 slot, partition 3, and the filename is new.image:

Router(config)# no boot system Router(config)# boot system flash slot0:3:new.image

Note If you omit the partition and filename variables, you are prompted for them.

Step 4 Set the configuration register to 0x2102 (the default setting), which indicates that the router should

attempt to boot a Cisco IOS image from Flash memory:

Router(config)# config-register 0x2102

Step 5 Exit global configuration mode:

Router(config)# exit

Step 6 Enter the copy running-config startup-config command to save the configuration changes to NVRAM. Step 7 Enter the reload command to reload the router. When the router reloads, it will boot the image

new.image from the Flash memory card in slot 0.

Erasing the Contents of a Flash Memory Card

To erase a partition or the entire contents of a Flash memory card, enter the command erase {slot0: | slot1:} [partition:]. Replace partition with the partition number. You cannot specify a filename. The

following example erases the contents of partition 2 of the card in slot 1.

Note Cisco recommends first displaying the contents of the partition that you plan to erase.

Installing and Formatting Compact Flash Memory Cards in Cisco 3631 Routers

This section describes how to install Compact Flash memory cards in Cisco 3631 routers, howto format the cards into a Class B Flash file system (low end file system) or a Class C Flash file system (similar to DOS), and how to perform file and directory operations in each file system. In Cisco 3631 routers, the Compact Flash memory card mounts on a connector on the CPU/mainboard. You can install a Compact Flash memory card with 32-, 64-, or 128-MB of memory.

This document contains the following sections:

• Preventing Electrostatic Discharge Damage, page 5-44

• Tools and Equipment Needed, page 5-44

• Compact Flash Memory Card Installation and Removal, page 5-45

• Formatting Procedures for Compact Flash Memory Cards, page 5-49

• File and Directory Procedures, page 5-51

Preventing Electrostatic Discharge Damage

Compact Flash memory cards are sensitive to electrostatic discharge (ESD) damage. ESD damage, which can occur when electronic cards or components are handled improperly, results in complete or intermittent failures.

Follow these guidelines to prevent ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• Place a removed Compact Flash memory card on an antistatic surface or in a static shielding bag. If

the card will be returned to the factory, immediately place it in a static shielding bag.

• Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages

on the body only; ESD voltages on clothing can still cause damage.

• Do not remove the wrist strap until the installation is complete.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohms).

Tools and Equipment Needed

You need the following tools and equipment to remove and install Compact Flash memory cards:

• ESD-preventive wrist strap

• Antistatic bag or mat

• Number 2 Phillips screwdriver or flat blade screwdriver

Formatting Procedures for Compact Flash Memory Cards

Cisco recommends that you format new Compact Flash memory cards to initialize them with either a Class B Flash file system or a Class C Flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the Flash.

The Class B Flash file system is also known as the low end file system (LEFS). The Class C Flash file system is similar to the standard DOS file system.

Note A Compact Flash memory card formatted with the standard DOS file system does not support booting

from the ROM monitor.

Determining the File System on a Compact Flash Memory Card

To determine the file system of a Compact Flash memory card in a Cisco 3631, enter the show flash: command.

If the content of the Compact Flash memory card displays, the card was formatted with a Class B Flash file system. If the geometry and format information of the card displays, the card was formatted with a Class C Flash file system.

The following example shows output for an internal Compact Flash memory card formatted with a Class C Flash file system:

When a file is deleted in the Class B Flash file system, the memory space occupied by the deleted file is not released until you enter the squeeze command. Although the memory space once occupied by the deleted file remains, the deleted file cannot be recovered. To release the memory space occupied by a deleted file, enter the squeeze flash: command.

Note The dir command does not show deleted files; the show command shows all files, including any

deleted files if the squeeze command has not been entered.
