Preface
Electrostatic discharge (ESD) and ESD protection: ESD can damage disk
drives, boards, and other parts. Perform all procedures using ESD protection
procedures. Some ESD protection can be provided by wearing an antistatic wrist
strap attached to a chassis ground⎯any unpainted metal surface⎯on your server
when handling parts.
ESD and handling boards: Always use ESD protection when handling ESD
sensitive hardware. Always handle boards carefully. Hold boards only by their edges.
After removing a board from its protective wrapper or from the server, install it
directly into the server or replace it directly into its protective wrapper. If you need to
set the board down, place it component side up on a grounded, static free surface.
Use a conductive foam pad if available. Do not set the board on the top of its anti-
static bag. Do not slide a board over any surface.
Installing or removing jumpers: A jumper is a small plastic encased conductor
that slips over two jumper pins. Some jumpers have a small tab on top that you can
grip with your fingertips or with a pair of fine needle nosed pliers. If your jumpers do
not have such a tab, take care when using needle nosed pliers to remove or install a
jumper; grip the narrow sides of the jumper with the pliers, never the wide sides.
Gripping the wide sides can damage the contacts inside the jumper, causing
intermittent problems with the function controlled by that jumper. Use caution when
removing a jumper so you do not bend or break any pins on the server board.
Removing server top cover: Unless otherwise noted in this document, only a
QUALIFIED SERVICE TECHNICIAN is authorized to remove the server's top
cover and to access any of the components inside the server. For proper cooling and
airflow, always install the server top cover before turning on the system. Operating
the system without the cover in place can lead to damage to system parts.
Risk of burns: Some exposed circuits exceed 240 VA when the system is
connected to a power source, and may cause burn injury if accidentally contacted.
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 the rack on slides. 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. A crush hazard exists should the rack tilt forward which could
cause serious injury.
Main AC power disconnects: Users 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).
Grounding the rack installation: To avoid the potential for an electrical shock
hazard, users must include a third wire safety-grounding conductor with the rack
installation. If the server power cord is plugged into an AC outlet that is part of the
rack, then users must provide proper grounding for the rack itself. If the server power
cord is plugged into a wall AC outlet, the safety-grounding conductor in the power
cord provides proper grounding only for the server. Users must provide additional,
proper grounding for the rack and other devices installed in it.
