The Installing Rack Products video provides a visual overview of operations required for configuring
a rack with rack-mountable components. It also provides the following important configuration steps:
•
Planning the site
•
Installing rack servers and rack options
•
Cabling servers in a rack
•
Coupling multiple racks
•
The Rack Products Documentation CD enables you to view, search, and print documentation for HP
and Compaq branded racks and rack options. It also helps you set up and optimize a rack in a
manner that best fits your environment.
If you intend to deploy and configure multiple servers in a single rack, refer to the white paper on high-
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 122 cm (48 in) in front of the rack.
•
Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
•
Leave a minimum clearance of 122 cm (48 in) from the back of the rack to the back of another rack
when racks are back-to-back.
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.
The Compaq 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, you must install the high airflow rack door
insert [P/N 327281-B21 (42U) or P/N 157847-B21 (22U)] to provide proper front-to-back airflow and
cooling.
