Installing and Configuring Jumpers &

Optional Components

This chapter describes the following:

• Jumper block locations and functions.

• Procedures to remove and install optional components.

• Information about replacing the battery.

Before You Begin

• Be sure to do each procedure in the correct order.

• Set up an equipment log to record the system model and serial numbers, all

installed options, and other information about the system. If you need this

information, it will be easier to consult the log than to open up and examine the

system.

• You will need a medium flat-bladed screwdriver and a jumper removal tool, such as

a pair of fine needle-nosed pliers. We recommend that you use an antistatic wrist

strap and a conductive foam pad when working on the board.

WARNING

The procedures in this chapter assume familiarity with the general

terminology associated with personal computers and with the safety

practices and regulatory compliance required for using and modifying

electronic equipment.

Disconnect the system from its power source and from any

telecommunications links, networks or modems before doing any of the

procedures described in this chapter. Failure to disconnect power,

telecommunications links, networks or modems before you open the system

or do any procedures can result in personal injury or equipment damage.

Some circuitry on the system board may continue to operate even though

the front panel power button is off.

CAUTION

Electrostatic discharge (ESD) can damage components. Do the procedures

described in this chapter only at an ESD workstation. If such a station is not

available, you can provide some ESD protection by wearing an antistatic wrist

strap and attaching it to a metal part of the system chassis.
