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, use 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.
