Heat Dissipation and Airflow Requirements
The following table lists the maximum rate of heat released from a system. In order to cool the system properly, ensure that adequate airflow travels through the system.
|
The direction of airflow is front to back for the main and expansion racks.
 | Caution - Do not restrict the movement of cool air from the air conditioner to the cabinet, or the movement of hot air out of the rear of the cabinet. |
Observe these additional requirements:
-
Allow a minimum clearance of 914 mm (36 inches) at the front of the rack, and 914 mm (36 inches) at the rear of the rack for ventilation. There is no airflow requirement for the left and right sides, or the top of the rack.
-
If the rack is not completely filled with components, cover the empty sections with filler panels.
