Rack-mounting Guidelines and Precautions

Observe the following guidelines and safety precautions during the rack-mount
installation.
l
Extend the rack's anti-tip foot prior to any work on the rack to prevent rack
tip-over, equipment damage, and injury.
WARNING
Lower the leveler feet at the four corners of the rack to
improve stability and prevent the rack from rolling away as
devices are inserted into their rack mounts. Failure to use the
anti-tip foot or the anti-tip device and leveler feet could result
in serious injury.
l
Uneven mechanical loading within the rack can cause hazardous
conditions. Plan the placement of equipment in the rack to make sure that
this problem does not occur.
◊
Install components from the bottom up.
◊
Place the heaviest components on the bottom of the rack.
CAUTION If other rack components are to be mounted in the rack below
the HP NetServer, install those components before starting to
mount the HP NetServer.
◊
Use HP Rack Assistant to plan the rack configuration and to check
power, weight, and stability of the configured rack. Download HP

assembly before rack-mounting the HP NetServer.
