HARDWARE INSTALLATION
Note:
Some components are optional and only available upon request.
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.
