Table 25. Environmental specifications
Fresh Air: temperature, humidity, altitude de-rating
Continuous
operation
10°C to 35°C (50°F to 95°F) at 10% to 80% relative humidity with 26°C (78.8°F) maximum
dew point (maximum wet bulb temperature). De-rate maximum allowable dry bulb
temperature at 1°C per 300m above 950m (1°F per 547 ft above 3117 ft).
Expanded
operation
When operating in the expanded temperature range, system performance may be impacted
and ambient temperature warnings may be reported on the LCD and in the System Event
Log.
≤ 10% of annual operating hours: 5°C to 10°C and 35°C to 40°C (with no direct sunlight on
the equipment) at 5% to 85% relative humidity with 26°C dew point (maximum wet bulb
temperature). Outside the standard operating temperature (10°C to 35°C), the system can
operate down to 5°C or up to 40°C for a maximum of 10% of its annual operating hours. For
temperatures between 35°C and 40°C (95°F to 104°F), de-rate maximum allowable dry bulb
temperature by 1°C per 175m above 950m (1°F per 319 ft above 3117 ft).
≤ 1% of annual operating hours: –5°C to 5°C and 40°C to 45°C (with no direct sunlight on
the equipment) at 5% to 90% relative humidity with 26°C dew point (maximum wet bulb
temperature). Outside the standard operating temperature (10°C to 35°C), the system can
operate down to –5°C or up to 45°C for a maximum of 1% of its annual operating hours. For
temperatures between 40°C and 45°C (104°F to 113°F), de-rate maximum allowable dry bulb
temperature by 1°C per 125m above 950m (1°F per 228 ft above 3117 ft).
Expanded operation restrictions:
 System must have six fans
 Processors not supported: 130W, 4-core processors, 135W processors, Intel Core
processors
