Temperature Guidelines
An ambient temperature range of 21
°
to 23
°
Celsius (70
°
to 74
°
Fahrenheit) is optimal for
server reliability and operator comfort. Most computer equipment can operate in a wide
temperature range, but approximately 22
°
Celsius (72
°
Fahrenheit) is recommended because it
is easier to maintain safe humidity levels. Operating in this temperature range provides a safety
buffer in the event that the air conditioning system is not running for a period of time.
Humidity Guidelines
The ambient relative humidity range of 45 to 50 percent is acceptable for safe data processing
operations. Most computer equipment can operate in a wide range (20 to 80 percent), but 45 to
50 percent is the recommended optimal range for the following reasons:

Helps protect computer systems from corrosion problems associated with high humidity
levels.
