ProLiant servers draw in cool air through the front rack door and expel warm air
through the rear rack door. Therefore, the front and rear rack doors must be
adequately ventilated to enable ambient room air to enter the cabinet, and the rear
door must be adequately ventilated to enable the warm air to escape from the cabinet.
CAUTION:
Do not block the ventilation openings.
When there is any vertical space in the rack not filled by servers or rack components,
the gaps between the components cause changes in airflow through the rack and
across the servers. Cover all gaps with blanks to maintain proper airflow.
Compaq branded 9000 and 10000 Series racks provide proper server cooling from
flow-through perforations in the front and rear rack doors that provide 64 percent
open area for ventilation.
CAUTION:
When using a Compaq branded 7000 Series rack, you must install the
high airflow rack door insert [P/N 327281-B21 (42U) and P/N 157847-B21 (22U)] to
provide proper front-to-back airflow and cooling.
CAUTION:
If a third-party rack is used, observe the following additional
requirements to ensure adequate airflow and to prevent damage to the equipment:
•
Front and rear doors: If your 42U server rack includes closing front and rear
doors, you must allow 5,350 sq cm (830 square inches) of holes evenly
distributed from top to bottom to permit adequate airflow (equivalent to the
required 64 percent open area for ventilation).
•
Side: The clearance between the installed rack component and the side panels
of the rack must be a minimum of 7 cm (2.75 inches).
CAUTION:
Always use blanks to fill empty vertical spaces in the rack. This
arrangement ensures proper airflow. Using a rack without blanks results in improper
cooling that can lead to thermal damage.
Temperature Requirements
To ensure continued safe and reliable equipment operation, install or locate the
system in a well-ventilated, climate-controlled environment.
