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.
