• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or

row of racks.

Hewlett Packard Enterprise servers draw in cool air through the front door and expel warm air through the
rear door. Therefore, the front and rear rack doors 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.

CAUTION:

To prevent improper cooling and damage to the equipment, do not block the ventilation openings.

When vertical space in the rack is 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.

The 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.

CAUTION:

When using a Compaq branded 7000 series rack, install the high airflow rack door insert (PN 327281-
B21 for 42U rack, PN 157847-B21 for 22U rack) 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 the 42U rack includes closing front and rear doors, you must allow 5,350 sq

cm (830 sq in) 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 in).

IMPORTANT:

The HPE ProLiant DL380 Gen10 Server cable management arm is not supported on Compaq branded
7000 series racks.

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position the system in a well-ventilated,
climate-controlled environment.

The maximum recommended ambient operating temperature (TMRA) for most server products is 35°C
(95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).
