Specification
10° C to 35° C (50° F to 95° F) with no direct sunlight
Derate the maximum temperature by 1°C per every 300 meters of altitude above
sea level.
Although the ASHRAE guidelines define multiple classes with different
Note
operating ranges, the recommended temperature and humidity operating
range is the same for each class. The recommended temperature and
humidity ranges are:
• Operating Temperature: 64.4°F to 80.6°F (18°C to 27°C)
For general information, see the
Planning Guide: Data Center Power and
Below -40° C or above 65° C (below -40° F or above 149° F)
Maximum rate of change (operating and non-operating) 20° C/hr (36° F/hr)
5° C to 40° C (41° F to 104° F) with no direct sunlight
Maximum allowable operating temperature derated
1° C/175 m (1° F/319 ft) above 950 m (3117 ft)
5° C to 45° C (41° F to 113° F) with no direct sunlight
Maximum allowable operating temperature derated
1° C/125 m (1° F/228 ft) above 950 m (3117 ft)
System performance may be impacted when operating in the
extended operating temperature range.
Operation above 40° C is limited to less than 1% of annual
operating hours.
Hardware configuration limits apply to extended operating temperature range.
8 to 90% and 24° C (75o F) maximum dew-point temperature, non-condensing
