On completion of any assembly or reassembly, perform a power-on test. If a fault
occurs, verify that the assembly or reassembly was performed correctly. If the
problem persists,
see “Solving Problems” on page 233 .
Static Precautions
An electrostatic discharge (ESD) can damage disk drives, option boards, and other
components. You can provide some ESD protection by wearing an anti-static wrist
strap attached to chassis ground when handling system components.
Electronic devices can be easily damaged by static electricity. To prevent damage, keep
them in their protective packaging when they are not installed in your system.
Assembly
The following subsection describes how to assemble your rack-mount server into a
standard 19-inch rack cabinet.
Before you begin select an appropriate location in your rack cabinet for the rack-mount
server. To improve rack stability, mount heavier items towards the bottom of the rack
cabinet. If the rack is a stand-alone unit and the rack is more than 75% filled with
components, consider installing an optional stabilizer kit.
Note: When planning your system configuration for the rack
cabinet you should consider the length of the cables that inter-
connect system components.
Warning

A
NCHOR 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.

POWER DISCONNECT
: You are responsible for install-
ing an AC power disconnect for the entire rack unit. This
main disconnect must be readily accessible, and it must be
labelled as controlling power to the entire unit, not just to the
server(s).

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 a
server power cord is plugged into an AC outlet that is part of
the rack, then you must provide proper grounding for the
rack itself. If server power cords are plugged into wall AC
