About Upgrading Your Computer System
The upgrading procedures described in the online manual, 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 telecommunications links, networks, or modems before you
open the system or follow any of the upgrading procedures described in the online manual. Failure to do so may
result in personal injury or equipment damage.
Electrostatic discharge (ESD) can damage disk drives, add-on cards, and other components. Follow the upgrading
procedures described in the online manual while working at an ESD workstation. If such a station is not available,
follow these precautions:
Avoid working in a carpeted area.
Do not handle materials that may produce or hold static electricity, such as cellophane wrappers.
Ground yourself by maintaining continuous contact with an unpainted metal portion of the chassis while
performing the procedure.
When removing a slot cover, be careful not to damage components on the system board or add-on cards. You may
need to temporarily remove add-on cards that are next to the slot cover you want to remove.
