Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. 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.
2. Disconnect power before making any configuration changes. The sudden rush of power
as you connect a jumper or install a card may damage sensitive electronic components.
