Environmental Specifications
This section provides the temperature/humidity requirements, noise emission, and air flow specifications for
the hp Integrity cx2600 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.
Nonoperating Environment
The system is designed to withstand ambient temperatures between –40°C to 70°C under nonoperating
conditions.
