Environmental specifications

NOTE For additional information about environmental certifications, refer to the Product Environmental Datasheet located with the Manuals & Documents on www.dell.com/support/home.

Table 1. Temperature specifications When the system is in continuous operation (for altitude less than 950 m or 3117 feet), the temperature specification ranges 10°C to 35°C (50–95°F) with no direct sunlight on the equipment. When the system is not in operation, the temperature specification is -40°C to 65°C (-40°F to149°F). For more information about fresh air, see the Expanded operating temperature section. The maximum temperature gradient for both operation and nonoperational systems is 20°C/h (36°F/h). Information about fresh air specification is described in the Expanded operating temperature section.
Temperature	Specifications
Storage	-40–65°C (-40–149°F)
Continuous operation (for altitude less than 950 m or 3117 ft)	10–35°C (50–95°F) with no direct sunlight on the equipment
Fresh air	For information about fresh air, see the Expanded operating temperature section.
Maximum temperature gradient (operating and storage)	20°C/h (68°F/h)

Table 2. Relative humidity specificationsFor a nonoperational system, the ambient relative humidity ranges from 5% to 95% with 33°C (91°F) maximum dew point. Atmosphere must be noncondensing at all times. For an operational system, the ambient relative humidity ranges from 10% to 80% with 29°C (84.2°F) maximum dew point.
Relative humidity	Specifications
Storage	5% to 95% RH with 33°C (91°F) maximum dew point. Atmosphere must be noncondensing at all times.
Operating	10% to 80% RH with 29°C (84.2°F) maximum dew point.

Table 3. Maximum vibration specificationsThe maximum vibration specification of an operational system is 0.26 Grms at 5 Hz to 350 Hz (all operation orientations).The maximum vibration specification of a nonoperational system is 1.88 Grms at 10 Hz to 500 Hz for 15 minutes (all six sides tested).
Maximum vibration	Specifications
Operating	0.26 G_rms at 5 Hz to 350 Hz (all operation orientations)
Storage	1.88 G_rms at 10 Hz to 500 Hz for 15 minutes (all six sides tested)

Table 4. Maximum shock pulse specificationsThe maximum shock specification of an operational system is six consecutively executed shock pulses in the positive and negative x, y, and z axis of 40 G for up to 2.3 ms. The maximum shock specification of a nonoperational system is six consecutively executed shock pulses in the positive and negative x, y, and z axis (one pulse on each side of the system) of 71 G for up to 2 ms.
Maximum shock pulse	Specifications
Operating	Six consecutively executed shock pulses in the positive and negative x, y, and z axis of 6 G for up to 11 ms.
Storage	Six consecutively executed shock pulses in the positive and negative x, y, and z axis (one pulse on each side of the system) of 71 G for up to 2 ms.

Table 5. Maximum altitude specificationsThe maximum altitude specification for an operational system is 3048 m (10,000 ft). The maximum altitude specification for a nonoperational system is 12,000 m (39,370 ft).
Maximum altitude	Specifications
Operating	3048 m (10,000 ft)
Storage	12,000 m (39,370 ft)

Table 6. Operating temperature derating specificationsIf the operating temperature of a system is up to 35°C (95°F), the maximum temperature is reduced by 1°C/300 m (1°F/547 feet) above 950 m (3,117 feet). If the operating temperature of a system is 35°C to 40°C (95°F to 104°F), the maximum temperature is reduced by 1°C/175 m (1°F/319 feet) above 950 m (3,117 feet). If the operating temperature of a system is 40°C to 45°C (104°F to 113°F), the maximum temperature is reduced by 1°C/125 m (1°F/228 feet) above 950 m (3,117 feet).
Operating temperature derating	Specifications
Up to 35°C (95°F)	Maximum temperature is reduced by 1°C/300 m (1°F/547 ft), above 950 m (3,117 ft).
35–40°C (95–104°F)	Maximum temperature is reduced by 1°C/175 m (1°F/319 ft), above 950 m (3,117 ft).
40–45°C (104–113°F)	Maximum temperature is reduced by 1°C/125 m (1°F/228 ft), above 950 m (3,117 ft).
