Product Number: BOOT-2500=

This document explains how to replace the boot ROMs in the Cisco 2500 series and AccessPro PC

card routers. The boot ROMs are the same for both the Cisco 2500 series and AccessPro PC card

routers.

Note Throughout this document, when referring to the Cisco 2500 series routers, the term “router”

means routers, access servers, and router/hubs.

This document contains the following sections:

• Preventing Electrostatic Discharge Damage, on page 1

• Removing the Cover or AccessPro PC Card, on page 2

• Replacing the Boot ROMs—All Models, on page 7

• Replacing the Cover or AccessPro PC Card, on page 20

• Cisco Connection Online, on page 22

Preventing Electrostatic Discharge Damage

Before replacing the boot ROMs, read the electrostatic discharge (ESD) instructions in this section

to prevent damage to the equipment. ESD is a discharge of stored static electricity that can damage

equipment and impair electrical circuitry. It occurs when electronic components are improperly

handled and can result in complete or intermittent failures.

Following are guidelines for preventing ESD damage:

• Before you open a chassis, ensure that power to the unit is OFF, but that the power cord is

connected to the wall receptacle. Having the power cord connected ensures a ground path for any

ESD voltages.

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