##### Environmental Specifications

Install and operate the server in a site with an ambient temperature range of 21°C (69.8°F) to 23°C (73.4°F), which is an optimal range for server reliability. At 22°C (71.6°F) it is easy to maintain safe relative humidity levels. Operating in this temperature range provides a buffer if the environmental support systems fail.

Operating the server in a site with ambient relative humidity levels between 45% and 50% prevents corrosion, provides an operating time buffer in the event of environmental control system failure, and helps avoid failures caused by static discharges that occur when relative humidity is too low.

Note - Electrostatic discharge is easily generated and less easily dissipated in areas where the relative humidity is below 35%, and becomes critical when levels drop below 30%.

The server has been tested to meet all functional requirements when operating in the operating environmental limits listed in the table below (all values are for a single, non-rackmounted server).

Parameter | Value
--- | ---
Operating temperature | 5°C to 35°C (41°F to 95°F)
Non-operating temperature | -40°C to 65°C (-40°F to 149°F)
Operating humidity | 10% to 90% relative humidity, 27°C (80.6°F) maximum web bulb, noncondensing
Non-operating humidity | Up to 93% relative humidity, 38°C (100.4°F) maximum web bulb, noncondensing
Operating altitude | Up to 3000 m (10,000 ft)1, maximum ambient temperature is derated by 2 degrees C for every 1 km (3.6 degree F per 3,280 ft); IEC 60068-2-13 Test M, and 60068-2-41 Test Z/BM
Non-operating altitude | Up to 12,000 m (40,000 ft); IEC 60068-2-13 Test M
Operating vibration | 0.15 G (vertical), 0.10 G (horizontal), 5 – 500 Hz, swept-sine
Non-operating vibration | 0.5 G (vertical), 0.25 G (horizontal), 5 – 500 Hz, swept-sine
Operating shock | 3.0 G, 11 ms, half-sine
Non-operating shock | Roll-off: 1-inch roll-off free fall, front to back rolling directions Threshold: 25 mm threshold height at 0.75 m/s impact velocity

1Except in China markets where regulations may limit installations to a maximum altitude of 2000 m.
