Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.

To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.

Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec -
tronic components.
