HP Integrity Superdome 2 utilizes variable speed fans to realize the most efficient use of air. The volume of air required varies with the temperature of the air supplied to the inlet of HP Integrity Superdome 2. The following table and chart illustrate the necessary volume of air to enable proper operation. IMPORTANT: Equipment orientation will best be served in a parallel fashion to the air flow supply and return. Supply air will flow down cold aisles which are parallel to equipment rows, and return air to CRAC through parallel air flow. Perpendicular air flow causes too much room mixing, places higher electrical loads on room, and can lead to unexpected equipment problems.

HP Integrity Superdome 2 utilizes variable speed fans to realize the most efficient use of air. The
volume of air required varies with the temperature of the air supplied to the inlet of HP Integrity
Superdome 2. The following table and chart illustrate the necessary volume of air to enable proper
operation.
IMPORTANT:
Equipment orientation will best be served in a parallel fashion to the air flow supply
and return. Supply air will flow down cold aisles which are parallel to equipment rows, and return
air to CRAC through parallel air flow. Perpendicular air flow causes too much room mixing, places
higher electrical loads on room, and can lead to unexpected equipment problems.
