Environmental
Conductive Dust
NOTE: Applies to data center and non-data center
environments.
Air must be free of conductive dust, zinc whiskers, or
other conductive particles.
Corrosive Dust
NOTE: Applies to data center and non-data center
environments.
• Air must be free of corrosive dust.
• Residual dust present in the air must have a
deliquescent point less than 60% relative humidity.
Gaseous Contamination
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Copper Coupon Corrosion Rate <300 Ã…/month per Class G1 as defined by ANSI/
ISA71.04-1985.
Silver Coupon Corrosion Rate <200 Ã…/month as defined by AHSRAE TC9.9.
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
• Do not perform a cold startup below 5 °C.
• The operating temperature specified is for a
maximum altitude of 3050 m (10,000 ft).
• Four redundant power supplies are required.
• Non Dell qualified peripheral cards and/or peripheral
cards greater than 25 W are not supported.
