This document describes how to install Cisco 2691, Cisco 3631, and Cisco 3700 CompactFlash memory

cards in Cisco modular routers which use Cisco 2691, Cisco 3631, or Cisco 3700 CompactFlash

memory. This document also contains procedures for formatting the CompactFlash cards with a Class B

Flash file system (low end file system) or a Class C Flash file system (similar to DOS), and it describes

how to perform file and directory operations in each file system. Some Cisco routers have an external

CompactFlash memory card that resides in a slot in the rear panel; some have an internal CompactFlash

memory card that mounts on a connector on the CPU/mainboard; and some have both. Cisco 2691,

Cisco 3631, and Cisco 3700 CompactFlash memory cards are available with 32, 64, or 128 MB of

memory.

Use this document with the Cisco 2600 Series, 3600 Series, and 3700 Series Regulatory Compliance and

Safety Information document, which shipped with your router. If you have questions or need help, refer

to the “Obtaining Documentation” section on page 31.

Preventing Electrostatic Discharge Damage

CompactFlash 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 CompactFlash 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 CompactFlash memory cards:

•ESD-preventive wrist strap

•Antistatic bag or mat

•Number 2 Phillips screwdriver or flat blade screwdriver (only for internally mounted CompactFlash

memory cards)

External CompactFlash Memory Card Installation and Removal

Complete the appropriate procedure below for installing or removing a CompactFlash memory card if

your Cisco router has an external CompactFlash memory card.

If you have questions or need assistance, see the “Obtaining Technical Assistance” section on page 32.

External CompactFlash memory-card slots are located as shown in Figure 1, Figure 2, and Figure 3.

Warning

Do not touch the power supply when the power cord is connected. For systems with a power

switch, line voltages are present within the power supply even when the power switch is OFF and

the power cord is connected. For systems without a power switch, line voltages are present within

the power supply when the power cord is connected. To see translations of the various warnings

that appear in this publication, refer to the Regulatory Compliance and Safety Information

document that accompanied this device.

Observe the following precaution if your router uses DC power:

Warning

Before performing any of the following procedures, ensure that power is removed from the DC

circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services

the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the

circuit breaker in the OFF position. To see translations of the various warnings that appear in this

publication, refer to the Regulatory Compliance and Safety Information document that

accompanied this device.

Complete the following procedure to remove the CPU/mainboard from the chassis:

Step 1 Power OFF the router. However, to channel ESD voltages to ground, do not unplug the power cable.

Caution The Cisco 3745 can have more than one power supply. Be sure that all power supplies are powered

OFF, and that the LEDs are all dark.

Step 2 Place the router on a flat surface so that the front panel is facing you, and open the small access panel at

the right-hand edge of the front panel.

Step 3 Loosen the two captive screws located behind the access panel. (See Figure 8.)

Step 4 Open the front panel to the straight-out position, and lift it off its hinges. (See Figure 8.)

Step 5 Loosen the captive retention screws; there is one at each side of the CPU/mainboard. (See Figure 9.)

Step 6 Pull the ejector levers at both sides, and carefully pull the CPU/mainboard straight out of the chassis.

Place it on an antistatic surface. (See Figure 9.)

Step 7 When you are ready to reinstall the CPU/mainboard, refer to the “Reinstalling a Plug-in

CPU/Mainboard” section on page 14.
