Environmental Requirements
The following table lists temperature, humidity and altitude requirements.

|
|
|
Temperature
|
5 to 32°C (41 to 89.6°F)
|
-40 to 70°C (-40 to 158°F).
|
For optimal rack cooling, data center temperatures from 21 to
23°C (70 to 47°F)
|
|
Relative humidity
|
10 to 90% relative humidity, noncondensing
|
Up to 93% relative humidity.
|
For optimal data center rack cooling, 45 to 50%,
noncondensing
|
|
Altitude
|
3048 m (10000 ft.) maximum
Except in China where regulations may limit
installations to a maximum altitude of 2000 m (6560
ft.).
|
12000 m (40000 ft.).
|
Ambient temperature is de-rated by 1 degree Celsius per 300 m
above 900 m altitude above sea level
