2 Hardware Upgrades

Serviceability Features

The computer includes features that make it easy to upgrade and service. No tools are needed for most

of the installation procedures described in this chapter.

Warnings and Cautions

Before performing upgrades be sure to carefully read all of the applicable instructions, cautions, and

warnings in this guide.

WARNING! To reduce the risk of personal injury or equipment damage from electrical shock,

hot surfaces, or fire:

Disconnect the power cord from the power outlet and allow the internal system components to

cool before touching.

Do not plug telecommunications or telephone connectors into the network interface controller

(NIC) receptacles.

Do not disable the power cord grounding plug. The grounding plug is an important safety feature.

Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.

To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes proper

workstation, setup, posture, and health and work habits for computer users, and provides

important electrical and mechanical safety information. This guide is located on the Web at

http://www.hp.com/ergo and on the Documentation and Diagnostics CD.

CAUTION Static electricity can damage the electrical components of the computer or optional

equipment. Before beginning these procedures, ensure that you are discharged of static

electricity by briefly touching a grounded metal object. See Appendix D,

Electrostatic

Discharge for more information.

When the computer is plugged into an AC power source, voltage is always applied to the system

board. You must disconnect the power cord from the power source before opening the computer

to prevent damage to internal components.
