up the port cover (B) and plug the cables into the

corresponding connectors.

Before You Begin

Read the following items before attempting to

upgrade or service the computer:

3These procedures 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.

3Set 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.

3HP recommends that you use an antistatic wrist

strap and a conductive foam pad when

working on the system.

3Disconnect the system from any

telecommunications links, networks,

or modems, and then disconnect the system

power source before performing any of the

procedures described in this guide. Failure to

do so before you open the system or do any

procedures can result in personal injury or

equipment damage.

Note:

Disconnect the modem/phone cable before

disconnecting the power cord from the system.

To gain access to the inside of the computer,

remove the side panel.

Warning:

Please read the

“Additional

Safety Information”

located at the end of

this document before installing and

connecting your system to the electrical

power system.
