COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
Airflow Requirements
Compaq ProLiant rackmountable 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.
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.
NOTE: If all of the vertical space in the rack is not filled by components, the gaps
that are left cause a change in airflow through the rack and across the components.
These gaps should be covered with blanking panels.
