Warning:
Electrostatic discharge (ESD) can damage your system board, proces-
sor, disk drives, add-in boards, and other components. Perform the
upgrade instruction procedures described at an ESD workstation only.
If such a station is not available, you can provide some ESD protec-
tion by wearing an antistatic wrist strap and attaching it to a metal
part of the system chassis. If a wrist strap is unavailable, establish
and maintain contact with the system chassis throughout any proce-
dures requiring ESD protection.

Warning:
When the Standby Power LED lit red, it indicates that there is power
on the system board. Power-off the PC then unplug the power cord
