Environmental specifications

NOTE: For additional information about environmental measurements for specific system configurations, see Dell.com/environmental_datasheets.

Table 1. Temperature specificationsWhen the system is in continuous operation (for altitude less than 950 m or 3117 ft), the temperature specification ranges from 10°C to 35°C (50°F to 95°F) with no direct sunlight on the equipment. NOTE: Maximum of 145 W 22 core processor is supported in systems with eight 2.5-inches drives, two PCI slot chassis, and 75 W single wide active GPU. When the system is not in operation, the temperature specification is –40°C to 65°C (–40°F to 149°F). The Maximum temperature gradient for both opertaion and non-opertaional 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°C to 65°C (–40°F to 149°F)
Continuous operation (for altitude less than 950 m or 3117 ft)	10°C to 35°C (50°F to 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)

Table 2. Relative humidity specificationsFor a non-operational system, the ambient relative humidity ranges from 5% to 95% with 33°C (91°F) maximum dew point. Atmosphere must be non-condensing 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 non-condensing at all times.
Operating	10% to 80% relative humidity 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 non-operational system is 1.88 Grms at 10 Hz to 500 Hz for 15 min (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 min (all six sides tested).

Table 4. Maximum shock specificationsThe maximum shock specification of an operational system is six consecutively executed shock pulses in the positive and negative x, y, and z axes of 40 G for up to 2.3 ms. The maximum shock specification of a non-operational system is six consecutively executed shock pulses in the positive and negative x, y, and z axes (one pulse on each side of the system) of 71 G for up to 2 ms.
Maximum vibration	Specifications
Operating	Six consecutively executed shock pulses in the positive and negative x, y, and z axes of 40 G for up to 2.3 ms.
Storage	Six consecutively executed shock pulses in the positive and negative x, y, and z axes (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 non-operational system is 12,000 m (39,370 ft).
Maximum altitude	Specifications
Operating	30482000 m (10,0006560 ft)
Storage	12,000 m (39,370 ft)

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