Important:
Electrostatic discharge (ESD) can damage your board, processor, disk drives, add-in
boards, and other components. Perform installation procedures at an ESD workstation
only. If such a station is not available, you can provide some ESD protection by wear-
ing 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 procedures requiring ESD protection.
Important:
When the Standby Power LED lights red, it indicates that there is power on the
system board. Power-off the PC then unplug the power cord prior to installing any de-
vices. Failure to do so will cause severe damage to the motherboard and components.
