Particulate contamination
Specifications
NOTE: Applies to data center and non-data center
environments.
• Residual dust present in the air must have
a deliquescent point less than 60% relative
humidity.

Table 27. Expanded Operating Temperature
Condition
Temperature
Continuous operation
5 °C to 40 °C at 5% to 85% RH with 29°C dew point.
NOTE: Outside the standard operating temperature (10°C to
35°C), the system can operate continuously down to 5°C or as
high as 40°C.
For temperatures between 35°C and 40°C, de-rate maximum allowable
temperature by 1 °C per 175 m above 950 m (1°F per 319 ft).
< 1% of annual operating hours –5°C to 45°C at 5% to 90% RH with 29°C dew point.
NOTE: 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, de-rate maximum
allowable temperature by 1 °C per 125 m above 950 m (1°F per 228 ft).
Expanded Operating
Temperature Restrictions
• For low-power CPUs (55 W/ 65 W), both the internal cooling fan
and the external cooling fan need to be installed.
• The operating temperature specified is for a maximum altitude of
3048 m (10,000 ft).
• GPU card is not supported.
• LRDIMM is not supported.
• Non-redundant power supplies are not supported.
• Cabled power supply units are not supported.
• Non Dell qualified peripheral cards and/or peripheral cards greater
than 25 W are not supported.
NOTE: When operating in the expanded temperature range, system performance may be impacted.
