5.1 Optimum Environment
When installing the server in a rack, select a location that meets the environmental
standards described in this section.
5.1.1 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.
Inspur 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.
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
