WARNING
Before doing the procedures in this chapter, make sure that
your system is powered off and unplug all AC power cords.
Failure to disconnect power before opening your system can
result in personal injury and equipment damage.
System power on/off.
The DC push-button on/off switch (a
convex button) on the front of the server system DOES NOT
turn off the system AC power. To remove power from
system, you must unplug the AC power cords (from wall
outlets or power supply).
Hazardous conditions, power supply.
Hazardous voltage,
current, and energy levels are present inside the power
supply. There are no user serviceable parts inside it;
servicing should be done by technically qualified personnel.
Hazardous conditions, devices & cables.
Hazardous
electrical conditions may be present on power, telephone,
and communication cables. Turn off the system and
disconnect the power cords, telecommunications systems,
networks, and modems attached to the system before
opening it. Otherwise, personal injury or equipment damage
can result.
!
CAUTION
Electrostatic discharge (ESD) and ESD protection.
ESD
can damage disk drives, boards, and other parts. This
system can withstand normal levels of environmental ESD
while you are hot-swapping SCSI hard drives or hot-
swapping a failed fan module or power supply. However, we
recommend that you do all procedures in this chapter only at
an ESD workstation. If one is not available, provide some
ESD protection by wearing an antistatic wrist strap attached
to chassis ground (any unpainted metal surface) on your
system when handling parts.
ESD and handling boards.
Always handle boards carefully.
They can be extremely sensitive to ESD. Hold boards only
by their edges. After removing a board from its protective
wrapper or from the system, place it component-side up on a
grounded, static-free surface. Use a conductive foam pad if
available but not the board wrapper. Do not slide board over
any surface.
Chassis covers, proper cooling and airflow.
For proper
cooling and airflow, always install the chassis top cover
before turning on the system. Operating it without the cover
in place can damage system parts.
Contact your sales representative or dealer for a list of approved optional
peripheral devices.
