Rack-Mounting the Chassis
This section describes how to rack-mount the chassis. The access server arrives with 19-inch
rack-mount brackets and larger brackets for use with a 23- or 24-inch rack. (See .) You can also
order telco rack-mount brackets (see ). The part number for telco brackets is AS52/3RM-
TELCO-19"=.
The following information will help you plan your equipment rack configuration:
•
Enclosed racks must have adequate ventilation. Ensure that the rack is not congested,
because each unit generates heat. An enclosed rack should have louvered sides and a fan to
provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn
upward into the intake ports of the equipment above.
•
When mounting a chassis in an open rack, ensure that the rack frame does not block the
intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when
it is seated in the rack.
•
Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through
the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which
can be found by experimenting with different configurations.
