NOTE: For additional information about environmental measurements for specific system
configurations, see dell.com/environmental_datasheets.
Standard Operating Temperature Continuous operation: 10 °C to 35 °C at 10% to
80% relative humidity (RH), with 26 °C max dew
point. De-rate maximum allowable dry bulb
temperature at 1 °C per 300 m above 900 m (1 °F
per 550 ft).
Expanded Operating Temperature
NOTE: When operating in the expanded
temperature range, system performance may
be impacted.
NOTE: When operating in the expanded
temperature range, ambient temperature
warnings may be reported on the LCD and in
the System Event Log.
< 10% of annual operating hours 5 °C to 40 °C at 5% to 85% RH with 26 °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 40 °C for a
maximum of 10% of its annual operating
hours.
For temperatures between 35 °C and 40 °C, de-
rate maximum allowable dry bulb 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 26 °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 dry bulb temperature by
1 °C per 125 m above 950 m (1 °F per 228 ft).
Expanded Operating Temperature Restrictions
• Install blades that fulfill the requirements for
expanded operating temperature range.
NOTE: For more information on the
blade-specific restrictions for the
expanded operating temperature range,
see the technical specifications in the
blade's Owner's Manual at dell.com/
support/manuals.
• 2700 W power supplies are supported as per
the power supply rated capacity.
