Back of the server 91.4 cm (36 inches)
Area above the rack 91.4 cm (36 inches)
Front of the server 123.2 cm (48.5 inches)
Environmental Requirements
The following table describes the environmental specifications for the server.
Caution -
Set conditions to the optimal temperature and humidity ranges to minimize the
chance of downtime due to component failure. Operating the servers for extended periods at or
near the operating range limits, or installing them in an environment where they remain at or
near nonoperating range limits could significantly increase hardware component failure.
Specification Operating Nonoperating
Ambient temperature

removable media)
■ 41˚F to 95˚F (5˚C to 35˚C) up to 2,953
feet (900 meters)
■ Optimal: 69.8˚F to 73.4˚F (21˚C to 23˚C)
Note - Maximum ambient operating
temperature is derated by 1 degree C per every
300 meters elevation beyond 900 meters, up to
a maximum altitude of 3,000 meters elevation.
