IMPORTANT:
The ring terminals must be UL approved and accommodate 12 gauge wires.
IMPORTANT:
The minimum nominal thread diameter of a pillar or stud type terminal must be 3.5
mm (0.138 in); the diameter of a screw type terminal must be 4.0 mm (0.157 in).
3.
Stack each same-colored pair of wires and then attach them to the same power source. The power cord
consists of three wires (black, red, and green).
For more information, see the documentation that ships with the power supply.
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.
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.
