Safety Recommendations

Follow these guidelines when working on equipment powered by electricity:

•Locate the room’s emergency power-OFF switch. Then, if an electrical accident occurs, you can

quickly shut the power OFF.

•Before working on the system, turn OFF the power and unplug the power cord.

•Disconnect all power before doing the following:

—Working on or near power supplies

—Installing or removing a router chassis or network processor module

—Performing a hardware upgrade

•Do not work alone if potentially hazardous conditions exist.

•Look carefully for possible hazards in your work area, such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

•Never assume that power is disconnected from a circuit. Always check.

•If an electrical accident occurs, proceed as follows:

—Use caution, and do not become a victim yourself.

—Turn OFF power to the system.

—If possible, send another person to get medical aid. Otherwise, determine the condition of the

victim and then call for help.

—Determine if the person needs rescue breathing or external cardiac compressions; then take

appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when

electronic printed circuit cards are improperly handled and can result in complete or intermittent

failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that

the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap,

ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis

frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage

and shocks, the wrist strap and cord must be used correctly. If no wrist strap is available, ground

yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which

should be between 1 and 10 megohms (Mohm).

Caution Before opening the chassis, be sure that you have discharged all static

electricity from your body and the power is OFF.

Warning Before working on a chassis or working near power supplies, unplug the power

cord on AC units; disconnect the power at the circuit breaker on DC units.

Cisco 2600 Series Memory Upgrade Configuration Note 5

Upgrading DRAM

This section describes how to upgrade DRAM on the system card. You might need to upgrade

DRAM for the following reasons:

•You have upgraded to a new Cisco IOS feature set or release.

•You are using very large routing tables or many protocols (for example, when the router is set up

as part of both a large external network and your internal network).

To see how much memory is currently installed in the router, enter the show versioncommand. Near

the middle of the resulting output, a message similar to the following displays:

Cisco XXXX(68030) processor (revision X) with 4092K/2048K bytes of memory.

This line shows how much memory is installed (in this example, 4092K/2048K). The ﬁrst number

represents primary memory and the second number represents shared memory.

Cisco 2600 DRAM

The Cisco 2600 series routers contain two 100-pin single DIMM sockets (or banks) for DRAM,

numbered 0 and 1. (See Figure 3.) Each socket can be ﬁlled with a dual, 100-pin DRAM DIMM.

You can use the memory-size iomemsoftware command to conﬁgure DRAM as a mixture of shared

memory, which is used for data transmitted or received by network modules and WAN interface

cards, and primary or main memory, which is reserved for the CPU. For further information about

this command, refer to the Cisco IOS conﬁguration guides and command references.

Memory Requirements

This section provides memory requirements for each Cisco IOS feature set supported by Cisco 2600

series routers. By default, all Cisco 2600 series routers contain 16 MB of DRAM and

4 MB of System Flash memory. The maximum amount of memory supported on Cisco 2600 series

routers is 64 MB of DRAM and 16 MB of system Flash memory. Table 1 summarizes the minimum

memory requirement for each Cisco IOS feature set.

Procedures for Recovering Flash Memory and System Images

If you have increased system Flash memory, or reduced DRAM in a Cisco 2600 series router, you might need to

reload the Cisco IOS image using one of the following ROM monitor commands:

•xmodem—Use this if the computer attached to your console has a terminal emulator that has xmodem

capability.

•tftpdnld—Use this if you have a TFTP server directly connected to the Ethernet 0 port.

For complete information on ROM monitor commands, refer to the Cisco 2600 Series Software Conﬁguration

Guide that accompanied your router package.

Caution To ﬁt the two sections together, it might be necessary to work them together at

one end and then the other, working back and forth; however, use care to prevent bending

the chassis edges.

14 Cisco 2600 Series Memory Upgrade Conﬁguration Note

Procedures for Recovering Flash Memory and System Images

Using the xmodem Command

If both the boot and system images are erased from Flash memory, the xmodem command establishes a

connection between a console and the router console or auxiliary port for disaster recovery.

xmodem [ﬁlename]—Establishes an xmodem connection between the console and the router. The optional

parameter ﬁlename speciﬁes the source ﬁle containing the Cisco IOS image.

Other options are:

-c—Use cyclic redundancy check (CRC-16).

-y—Use Ymodem transfer protocol.

-r—Copy the image to DRAM for launch.

-x—Do not launch image on completion of download.

Using the tftpdnld Command

The tftpdnld command downloads a Cisco IOS software image from a remote server into Flash memory using

TFTP.

tftpdnld—Begins the TFTP copy command.

The following variables are required:

IP_ADDRESS—The IP address for the router you are using.

IP_SUBNET_MASK—The subnet mask for the router you are using.

DEFAULT_GATEWAY—The default gateway for the router you are using.

TFTP_SERVER—The IP address of the server from which you want to download the image ﬁle.

TFTP_FILE—The name of the ﬁle that you want to download.

The following variables are optional:

TFTP_VERBOSE—Print setting. 0=quiet, 1=progress, 2=verbose. The default is 1.

TFTP_RETRY_COUNT—The retry count for ARP and TFTP. The default is 7.

TFTP_TIMEOUT—The overall timeout of the operation in seconds. The default is 2400 seconds.

TFTP_CHECKSUM—Performs a checksum test on the image. 0=no 1=yes The default is 1.

The syntax for specifying the variables is:

VARIABLE_NAME=value

Cisco 2600 Series Memory Upgrade Configuration Note 15
