Rack-Mounting the Chassis

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.
