Airflow Requirements
The Compaq ProLiant DL760 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 rack panels.
High Airflow Rack Door Insert
The increased power of new processor technology requires increased cooling
efficiency for rack-mounted servers. The new Compaq Rack 9000 series
provides enhanced airflow for maximum cooling, allowing these racks to be
fully loaded with servers using the latest processors.
When installing this server in Compaq Rack 7000 and 4000 series, the new
processor technology requires the installation of a new Compaq High Airflow
Rack Door Insert, if the rack has a LEXAN front door.
