•
Be sure enclosed racks have adequate ventilation. Make sure that the rack is not 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 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 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.
