1.4 Safety precautions
Follow these simple precautions to protect yourself from harm and your
PC from damage.
1. To avoid electric shock, always disconnect the power from your
PC chassis before you work on it. Do not 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.
3. Always ground yourself to remove any static charge before you
touch your CPU card. Be particularly careful not to touch the chip
connectors. Modern integrated electronic devices, especially CPUs
and memory chips, are extremely sensitive to static electric
discharges and fields. Keep the card in its antistatic packaging
when it is not installed in the PC, and place it on a static dissipa-
tive mat when you are working with it. Wear a grounding wrist
strap for continuous protection.
