Environmental Requirements

This section describes the environmental specifications for the server.

Caution:

Set conditions to the optimal temperature and humidity ranges to minimize the chance of downtime due to component failure. Operating the servers for extended periods at or near the operating range limits, or installing them in an environment where they remain at or near nonoperating range limits could significantly increase hardware component failure.

Specification	Operating	Nonoperating
Ambient temperature (does not apply to removable media)	41˚F to 95˚F (5˚C to 35˚C) up to 2,953 feet (900 meters) Optimal: 69.8˚F to 73.4˚F (21˚C to 23˚C) Maximum ambient operating temperature is derated by 1 degree C per every 300 meters elevation beyond 900 meters, up to a maximum altitude of 3,000 meters elevation.	–40˚F to 154˚F (–40˚C to 68˚C)
Relative humidity	10% to 90% noncondensing, short term 25˚F to 113˚F (–5˚C to 55˚C) 5% to 90% noncondensing, but not to exceed 0.024 kg of water per kg of dry air (0.053 lbs water/2.205 lbs dry air)	Up to 93% noncondensing 95˚F (35˚C) maximum wet bulb
Altitude	Maximum 9,840 feet (3,000 meters) at 95˚F (35˚C) Note: In China markets, regulations might limit installations to a maximum altitude of 6,562 feet (2,000 meters).	Maximum 39,370 feet (12,000 meters)
Acoustic Noise	Maximum condition: 8.1 Bels Idle condition: 5.8 Bels	Not applicable
Vibration	0.15 G (z-axis) 0.10 G (x-, y-axes), 5-500Hz swept sine IEC 60068-2-6 Test FC	0.5 G (z-axis) 0.25 G (x-, y-axes), 5-500Hz swept sine IEC 60068-2-6 Test FC
Shock	3 Gs, 11 ms half-sine IEC 60068-2-27 Test Ea	Roll-off: 1.25-inch roll-off free fall, front to back rolling directions Threshold: 13 mm threshold height at 0.65 m/s impact velocity ETE-1010-02 Rev A
