HARDWARE INSTALLATION
Note:
Specifications of these components are model-specific. Please
refer to the specifications for detail.
Important:
Electrostatic discharge (ESD) can damage your board, proces-
sor, 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 wearing an antistatic wrist strap and attaching it to a metal
part of the system chassis. If a wrist strap is unavailable, es-
tablish and maintain contact with the system chassis through-
out 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 compo-
nents.
