Dell 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:
 Maximum 95W processor is supported.
 Dell PERC H710 and H710P cards are not supported in dual-processor configurations.
 When populating the blade slots in the enclosure with only PowerEdge M620 blades:
— Dual-processor blade servers with PERC H310 cards cannot be mixed with single-
processor blades.
— To support a PERC H310 card in a dual-processor configuration, the blade slots in
the M1000e enclosure must be installed with M620 blades or a combination of
blade blanks and M620 blades.
The PowerEdge M620 blades must be installed with 97 mm wide heat sinks.
 Non Dell qualified peripheral cards and/or peripheral cards greater than 25W are not
supported.
