Planning the Server Installation Space and Airflow Requirements Tower Server In a tower configuration, leave at least a 7.6-cm (3-inch) clearance space at the front and back of the server for proper ventilation. Rack Server To allow for servicing and adequate airflow, observe the following spatial requirements when deciding where to install a Compaq branded, Telco, or third-party rack: • Leave a minimum clearance of 63.5 cm (25 inches) in front of the rack. • Leave a minimum clearance of 76.2 cm (30 inches) behind the rack. • Leave a minimum clearance of 121.9 cm (48 inches) 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. IMPORTANT: Do not block the ventilation openings. When there is any vertical space in the rack 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. 2-4 HP ProLiant ML370 Generation 3 Server Setup and Installation Guide

HP ProLiant ML370 Generation 3 Server Setup and Installation Guide
Space and Airflow Requirements
Tower Server
In a tower configuration, leave at least a 7.6-cm (3-inch) clearance space at the front
and back of the server for proper ventilation.
Rack Server
To allow for servicing and adequate airflow, observe the following spatial
requirements when deciding where to install a Compaq branded, Telco, or third-party
rack:
•
Leave a minimum clearance of 63.5 cm (25 inches) in front of the rack.
•
Leave a minimum clearance of 76.2 cm (30 inches) behind the rack.
•
Leave a minimum clearance of 121.9 cm (48 inches) 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.
IMPORTANT:
Do not block the ventilation openings.
When there is any vertical space in the rack 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.
