Note:
Specifications of these components are model-specific. Please refer to the specifi-
cations for detail.
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 pro-
tection 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 procedures requiring ESD protection.

Standby Power LED

Important:
When the Standby Power LED lights up, it indicates that there is power on the
system board. Power-off the PC then unplug the power cord prior to installing any
devices. Failure to do so will cause severe damage to the motherboard and com-
ponents.
