Setting up the system rack
Important! Observe the electrostatic discharge (ESD) precautions
indicated on page 35 when perfoming the following procedures.
Do not attempt the procedures described in the following sections
unless you are a qualified technician.
Equipment rack precautions
Follow the rack manufacturer's safety and installation instructions for
proper rack installation.
The following additional rack safety installation measures should be
considered:
• Anchor the equipment rack
The equipment rack must be anchored to an unmovable suitable
support to prevent the rack from falling over when one or more
systems are fully extended out of the rack assembly. You must also
consider the weight of any other devices installed in the rack
assembly. The equipment rack must be installed according to the
manufacturer's instructions.
• Main 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 system(s).
• Earth ground the rack installation
To avoid the potential for an electrical shock hazard, the rack
assembly itself must be suitably earth grounded, according to your
local regional electrical codes. This typically will require the rack to
have its own separate earth ground. We recommend you consult
your local approved electrician.
