Installation

Sequence

It is very important that you follow this sequence of steps to ensure the proper
installation of any optional equipment. For more information about Computer Setup,
refer to the Computer Setup (F10) Utility Guide. If the computer is powered on, turn
it off and disconnect the power cord from the wall outlet.

WARNING: To reduce the risk of personal injury from electrical shock
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet, and allow the internal system components to cool before touching.

WARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications/telephone connectors into
the network interface controller (NIC) receptacles.

CAUTION: Static electricity can damage the electronic components of
the computer or optional equipment. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. Refer to Appendix E “Electrostatic Discharge” in this
guide for additional information on preventing electrostatic discharge
