Optimum environment

When installing the server, select a location that meets the environmental
standards described in this section.

Space and Airflow Requirements

To allow for servicing and adequate airflow, observe the following space and
airflow requirements when deciding where to install a rack:
•
Leave a minimum clearance of 76.2 cm (30 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.
HP servers draw in cool air through the front and expel warm air through the
rear. Therefore, the front and rear rack doors must be adequately ventilated to
allow ambient room air to enter, and allow the warm air to escape from the
cabinet.
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.
