Supported PCIe card power—PCIe card temperatures and power ratings must meet following requirements:
System ambient after altitude
derating (°C/°F)
Maximum supported power
dissipation (W) for 85°C
(185°F) or above still air rated
PCIe cards
Maximum supported power
dissipation (W) for 70°C
(158°F) still air rated PCIe
cards

NOTE: PCIe cards must support still air environment and must not require active cooling.
NOTE: PCIe cards rated above 25 W are not supported regardless of temperature rating.
NOTE: If a PCIe card is rated at a temperature that is not shown in the table, use interpolation to calculate the maximum
supported power.
NOTE: If a PCIe card is rated at a temperature greater than 85°C (185°F), it shall be treated as an 85°C (185°F) rated
card in determining the supported power.

Temperature range:
Operating (with a maximum temperature gradation of
15°C per hour)
• -30°C to 70°C (-22°F to 158°F) when connected to a 24V
AC/DC power source.
• 0°C to 40°C (32°F to 104°F) when connected to a power
adapter or battery.
NOTE: The maximum operating temperature is derated
1°C/305m(1000ft) above sea level altitude.
Non-operating -40°C to 85°C (-40°F to 185 °F)
Relative humidity (maximum):
Operating (with maximum humidity gradation of 10%
per hour)
10% to 90% (non-condensing)
Non-operating ((with maximum humidity gradation of
10% per hour)
5% to 95% (non-condensing)
Altitude (maximum, unpressurized):
