Temperature Specications
Storage –40°C–65°C (–40°F-149°F)
Continuous operation (for altitude less than 950 m or 3117 ft) 10°C–35°C (50°F-95°F) with no direct sunlight on the equipment.
Fresh air For information about fresh air, see Expanded Operating
Temperature section.
Maximum temperature gradient (operating and storage) 20°C/h (68°F/h)

Air ltration Data center air ltration as dened by ISO
Class 8 per ISO 14644-1 with a 95% upper
condence limit.
NOTE: This condition applies only to data center environments. Air ltration requirements do not apply to IT equipment
designed to be used outside a data center, in environments such as an oce or factory oor.
NOTE: Air entering the data center must have MERV11 or MERV13 ltration.
Conductive dust Air must be free of conductive dust, zinc
whiskers, or other conductive particles.
NOTE: This condition applies to data center and non-data center environments.
Corrosive dust Air must be free of corrosive dust.
Residual dust present in the air must have a deliquescent point less than 60% relative humidity.
NOTE: This condition applies to data center and non-data center environments.
