Environmental Specifications

This section provides the temperature/humidity requirements, noise emission, and air flow specifications for 
the HP Server.

Temperature and Humidity Specifications

Ambient intake air temperature is often different from ambient room temperature; you should measure the 
operating temperature and humidity directly in front of the cabinet cooling air intakes rather than just 
checking ambient room conditions.

NOTE

Operating ranges refer to the ambient air temperature and humidity measured at the cabinet 
cooling air intake vents.

Acoustic Noise Specification

The acoustic noise specification for the HP Server is as follows:

< 60 db LpA (sound pressure level at bystander position)

The above level is appropriate for dedicated computer room environments, not office environments.

Care should be taken to understand the acoustic noise specifications relative to operator positions within the 
computer room or when adding HP Servers to computer rooms with existing noise sources.

Air Flow

The recommended cabinet air intake temperature is between 68

o

F and 77

o

F (20

C and 25
