Environmental Specifications
This section provides the temperature and humidity requirements, noise emission, and air flow
specifications for the server.
Temperature and Humidity
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.
Operating Environment
The system is designed to run continuously and meet reliability goals in an ambient temperature
of 5°C -40°C at sea level. The maximum allowable temperature is derated 1°C per 1,000 feet of
elevation above 5,000 feet above sea level up to 30°C at 10,000 feet. For optimum reliability and
performance, the recommended operating range is 20°C to 25°C and 40%-50% relative humidity.
Environmental Temperature Sensor
To ensure that the system is operating within the published limits, the ambient operation
temperature is measured using a sensor placed on the front panel LED status board. Data from
the sensor is used to control the fan speed and also to initiate system overtemp shutdown.
Non-operating Environment
The system is designed to withstand ambient temperatures between -40°C to 70°C under
nonoperating conditions.
