Configuration Factors

Airflow Requirements

HP rack-mountable products typically draw in cool air through the front and exhaust
warm air out through the rear of the rack. The front door of the rack, therefore, must
be adequately ventilated to allow ambient room air to enter the rack, and the rear
door must be adequately ventilated to allow the warm air to escape the rack. Do not
block the ventilation apertures.
Fan Kits
If additional cooling is required, fan kits can be used to draw heated air from the rear
of the rack, out through the top.
Blanking Panels
If the front of the rack is not completely filled with components, the remaining gaps
between the components can cause changes in the airflow that adversely affect
cooling within the rack. Cover these gaps with blanking panels.
