Airflow Requirements

Securing the Mounting Hardware to the
Server and Rack
The ProLiant ML350 Generation 2 server draws cool air in through the front
of the chassis and exhausts warm air out through the rear of the chassis.
Therefore, the front of the rack 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.
Compaq 9000 Series racks provide proper server cooling from flow-through
perforations, ensuring 64 percent open area for ventilation. Refer to the
documentation provided with Compaq 7000 Series racks for guidelines on
meeting airflow requirements.
CAUTION: When using a Compaq 7000 Series rack, you must install the
high-airflow rack door insert [Part Number 327281-B21 (42U) and Part Number
157847-B21 (22U)] to provide proper front-to-back airflow and cooling and
prevent damage to the equipment.
