Overview of Server Installation
Rack Environment
To allow for servicing and adequate airflow, observe the following spatial and
environmental requirements when selecting a site for your rack-mounted server:
Select a sturdy, level installation site that includes dedicated and properly
grounded (earthed) circuits, air conditioning and electrostatic discharge (ESD)
protection.

Leave a minimum clearance of 63.5 cm (25.0 inches) in front of the rack.
Leave a minimum clearance of 76.2 cm (30.0 inches) behind the rack.
Leave a minimum clearance of 121.9 cm (48.0 inches) from the back of the rack
to the back of another rack or row of racks.
HP servers draw in cool air through the front door of the rack and expel warm air
through the rear door. Therefore, the front door 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.
IMPORTANT:
Do not block the ventilation openings.
When there is any vertical space in the rack not filled by a server or rack component,
the gaps between the components cause changes in airflow through the rack and
across the servers. Cover all gaps with blanking panels to maintain proper airflow.
CAUTION:
Always use blanking panels to fill empty vertical spaces in the rack. This
arrangement ensures proper airflow. Using a rack without blanking panels results in
improper cooling that can lead to thermal damage.
Compaq branded 9000 and 10000 Series racks provide proper server cooling from
flow-through perforations in the front and rear doors that provide 64 percent open
area for ventilation. Refer to the rack documentation provided with Compaq branded
7000 Series racks for guidelines on meeting airflow requirements.
CAUTION:
When using a Compaq branded 7000 Series rack, you must install the
high-airflow rack door insert [Part Number 327281-B21 (42U) and Part Number
157847-B21 (22U)] to provide proper front-to-back airflow and cooling to prevent
damage to the equipment.
