COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
CAUTION: To reduce the risk of damage to the equipment when
installing third-party options:
Ensure that the option equipment does not impede airflow to
the Rack-Mountable ProLiant Servers or increase the internal
rack temperature beyond the Compaq specified maximum
rating.
Ensure that the Manufacturer’s Maximum Recommended
Ambient Operating Temperature of the option equipment is
not exceeded when installed in the rack.
Airflow Requirements
Compaq ProLiant rackmount 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.
Slide: 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.
Blanking Panels
If all of the vertical space in the rack is not filled by components, the gaps that
are left will cause a change in airflow through the rack and across the
components. These gaps need to be covered with blanking panels.
