Installing Your Unit in a Rack
Installing Your Unit in a Rack

The rack (which is not included with the unit) should provide sufficient
vertical clearance to insert the unit. The height of the unit is two rack
units (2U) high or about 3 1/2 inches.

All electrical cabling can be connected only through the back panel.
There mounting brackets are available in three formats:

For 19-inch racks

For 21-inch (ETSI) racks

For 23-inch racks.
The brackets have several rows of holes for more installation versatility. You
can install the unit with its front panel flush with the front of the rack, install
it forward, or even recessed in the rack.

ARNING

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. 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.

Mounting of the unit in a rack or cabinet should be such that a
hazardous condition is not achieved due to uneven mechanical
loading. The fully-configured unit is heavy. Use caution when
manipulating the unit. A lifting mechanism may be required for
installation.
I
MPORTANT
Ensure that you use the type of mounting brackets that
corresponds to the width of your rack.
