2-6 Compaq ProLiant 8500 Servers Setup and Installation Guide Airflow Requirements The Compaq ProLiant 8500 server draws cool air in through the front door and exhausts warm air out through the rear door. 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 ventilated adequately 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: s Front: The rack door should have 120 square inches of holes evenly distributed from top to bottom to permit adequate air flow. s Side: The clearance between the installed module and the side panels of the rack should be a minimum of 2.75 inches. s Rear: The clearance between the back of the rack and the wall should be a minimum of 30 inches and the equipment should be operating without a rear door. CAUTION: If all of the vertical space in the rack is not filled by components, the gaps left will cause a change in airflow through the rack and across the components. These gaps need to be covered with blanking panels.

Compaq ProLiant 8500 Servers Setup and Installation Guide
Airflow Requirements
The Compaq ProLiant 8500 server draws cool air in through the front door and
exhausts warm air out through the rear door. 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 ventilated adequately 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 rack door should have 120 square inches of holes evenly
distributed from top to bottom to permit adequate air flow.
■
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 and the equipment should be operating without a
rear door.
CAUTION:
If all of the vertical space in the rack is not filled by components, the
gaps left will cause a change in airflow through the rack and across the
components. These gaps need to be covered with blanking panels.
