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 airflow 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° to 35° 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° to 25° C. This meets or exceeds the requirements for Class 2 in the corporate and ASHRAE standard. See Table 2-8 (page 32) for an example of the ASHRAE thermal report.
