Safety Guidelines
H
AZARDOUS CONDITIONS
,
DEVICES AND CABLES
: Hazardous
electrical conditions may be present on power, telephone,
and communication cables. Turn off the server and
disconnect telecommunications systems, networks,
modems, and each power cord attached to the server
before opening it. Otherwise, personal injury or
equipment damage can result.

CAUTIONS
E
LECTROSTATIC DISCHARGE
(ESD)
AND
ESD
PROTECTION
:
ESD can damage disk drives, add-in boards, and other
components. We recommend doing all procedures in this
manual only at an ESD workstation. If one is not available,
you can provide some ESD protection by wearing an
antistatic wrist strap attached to chassis ground of the
server—any unpainted metal surface—when handling
components.
H
ANDLING BOARDS AND MODULES
: Boards and modules can
be extremely sensitive to ESD and always require careful
handling. After removing a board or module from its
protective wrapper or from the server, place it
component-side up on a nonconductive, static-free surface.
If you place the system board on a conductive surface, the
battery leads may short out. If they do, this will result in a
loss of CMOS data and will drain the battery. Do not slide
a board or module over any surface.
C
OOLING AND AIRFLOW
: Operating the server with the covers
removed can damage the server components. For proper
cooling and airflow, always replace the covers before
turning on the server.
