Airflow Requirements - Compaq ProLiant 5500 Setup And Installation Manual

Airflow Requirements

Compaq ProLiant rack mount servers draw cool air in through the front door
and exhaust warm air out the rear. Therefore, the front door of the rack must be
adequately ventilated to allow ambient room air to enter the cabinet, and the
rear door must be adequately ventilated to allow the warm air to escape from
the cabinet. Do not block the ventilation apertures.
NOTE: If all of the vertical space in the rack is not filled by servers, the gaps
that are left cause a change in airflow through the rack and across the servers.
These gaps should be covered with blanking panels.
For use with Pentium II Xeon and Pentium III Xeon processor-based servers only
CAUTION: If a third-party rack is used, the following minimum
requirements should be observed to ensure adequate airflow and
to prevent damage to the equipment:
Front: The front must have a minimum of 25 inches of
unrestricted ventilation.
Side: The clearance between the installed module and the side
panels of the rack should be a minimum of 2.75 inches.
Rear: The clearance between the back of the rack and the wall
should be a minimum of 30 inches. The equipment should
be operating without a rear door.
