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.
  • Allow processor performance degrade.
  • Non-redundant power supplies are not supported.
  • Non Dell qualified peripheral cards and/or peripheral cards greater than 25 W are not supported.
  • Maximum altitude for the operating temperature must be 3050 m (10,000 ft).

Particulate Contamination
  • NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseous contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits specified below and are the reason for the damage and/or failures to your equipment, it may be necessary for you to re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation of environmental conditions will be the responsibility of the customer.
  Air Filtration
  • NOTE: Applies to data center environments only. Air filtration requirements do not apply to IT equipment designed to be used outside a data center, in environments such as an office or factory floor.
Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit.
  • NOTE: Air entering the data center must have MERV11 or MERV13 filtration.
  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 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
  Silver Coupon Corrosion Rate <200 Å/month as defined by AHSRAE TC9.9.
