Note 3: User Expected Maximum Power: (Input power at the ac input expressed in Watts and
Volt-Amps.)
The measured maximum worst case power consumption. This number represents the largest
power consumption that HP engineers were able to produce for the server with any combination
of hardware under laboratory conditions using aggressive software applications designed
specifically to work the system at maximum load. This number can safely be used to compute
thermal loads and power consumption for the system under all conditions.

Environmental Specifications

This section provides the environmental, power dissipation, noise emission, and air flow
specifications for the server.

Temperature and Humidity

The cabinet is actively cooled using forced convection in a Class C1-modified environment. The
recommended humidity level for Class C1 is 40 to 55% relative humidity (RH).

Operating Environment

The system is designed to run continuously and meet reliability goals in an ambient temperature
of 5° C–32° C at sea level. The maximum allowable temperature is derated 1° C per 1,000 feet of
elevation above 3,000 feet above sea level up to 25° C at 10,000 feet. For optimum reliability and
performance, the recommended operating range is 20° C to 25° C. This meets or exceeds the
requirements for Class 2 in the corporate and ASHRAE standard. See
example of the ASHRAE thermal report.
