Rack planning resources
The rack resource kit ships with all HP branded or Compaq branded 9000, 10000, and H9 series
racks. For more information on the content of each resource, refer to the rack resource kit
documentation.
If you intend to deploy and configure multiple servers in a single rack, refer to the white paper on
high-density deployment at the HP website (http://www.hp.com/products/servers/platforms).
Optimum environment
When installing the server in a rack, 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 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.
HP 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
