Rack Configuration Considerations

Consider the following when planning a rack configuration:
If you are mounting a chassis in an open rack, make sure that the rack frame does
l
not block the intake or exhaust ports.
Be sure enclosed racks have adequate ventilation. Make sure that the rack is not
l
overly congested as each chassis generates heat. An enclosed rack should have
louvered sides and a fan to provide cooling air.
In an enclosed rack with a ventilation fan in the top, heat generated by equipment
l
near the bottom of the rack can be drawn upward and into the intake ports of the
equipment above it in the rack. Ensure that you provide adequate ventilation for
equipment at the bottom of the rack.
Baffles can help to isolate exhaust air from intake air, which also helps to draw
l
cooling air through the chassis. The best placement of the baffles depends on the
airflow patterns in the rack. Experiment with different arrangements to position the
baffles effectively.
