6 SC5000 Rack Kit Installation Guide
CAUTIONS
ELECTROSTATIC DISCHARGE (ESD) AND ESD PROTECTION: ESD can
damage disk drives, add-in boards, and other components. This server can
withstand normal levels of environmental ESD while hot-swapping SCSI
hard disk drives. However, we recommend doing all procedures in this
manual only at an ESD-protected 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
baseboard on a conductive surface, the battery leads can 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.
S
ERVER COOLING 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.
Equipment Rack Precautions
WARNINGS
ANCHOR THE EQUIPMENT RACK: The equipment rack must be anchored
to an unmovable support to prevent it from falling over when one or
more servers are extended in front of it on slide assemblies. The anchors
must be able to withstand a force of up to 113 kg (250 lbs.). You must
also consider the weight of any other device installed in the rack.
M
AIN AC POWER DISCONNECT: You are responsible for installing an
AC power disconnect for the entire rack unit. This main disconnect
must be readily accessible, and it must be labeled as controlling power to
the entire unit, not just to the server(s).
G
ROUNDING THE RACK INSTALLATION: To avoid the potential for an
electrical shock hazard, you must include a third wire safety grounding
conductor with the rack installation. If server power cords are plugged
into AC outlets that are part of the rack, then you must provide proper
grounding for the rack itself. If server power cords are plugged into
wall AC outlets, the safety grounding conductor in each power cord
provides proper grounding only for the server. You must provide
additional, proper grounding for the rack and other devices installed
in it.
