Air Quality Specifications; Acoustic Noise Specifications - HP Integrity Superdome 2 16-socket Service Manual

Because these temperatures might be significantly higher than the temperatures of the other
equipment in the data center, to not over-cool the air, you might have to adjust the set-points of
the CRACs or CRAHs higher. Most standalone CRACs and CRAHs use return side temperature
regulation rather than supply side. Since the supply side air temperature is the parameter of interest
to meet the 15-32 °C limits for the proper operation of Superdome2, you might have to increase
the return air set-points to maximize the capacity of the CRACs or CRAHs.
IMPORTANT:
you do not exceed the actual inlet temperature specified for any equipment.
