Environmental specifications
NOTE: For additional information about environmental certifications, refer to the Product Environmental Datasheet located
with the Manuals & Documents on Dell Support.
Table 23. Continuous operation specifications for ASHRAE A2
Temperature Specifications
Allowable continuous operations
Temperature ranges for altitudes <= 900 m (<=
2953 ft)
10–35°C (50–95°F) with no direct sunlight on the equipment
Humidity percent ranges (non-condensing at all
times)
8% RH with -12°C minimum dew point to 80% RH with 21°C (69.8°F)
maximum dew point
Operational altitude de-rating Maximum temperature is reduced by 1°C/300 m (1.8°F/984 Ft) above 900
m (2953 Ft)
NOTE: Certain system hardware configurations may require operating temperatures to be less than 35°C. For more
information, see the Thermal air restrictions section.
Table 24. Shared requirements across all categories
Temperature Specifications
Allowable continuous operations
Maximum temperature gradient (applies to both
operation and non-operation)
20°C in an hour* (36°F in an hour) and 5°C in 15 minutes (41°F in 15
minutes), 5°C in an hour* (41°F in an hour) for tape
NOTE: * - Per ASHRAE thermal guidelines for tape hardware, these are
not instantaneous rates of temperature change.
Non-operational temperature limits -40 to 65°C (-104 to 149°F)
Non-operational humidity limits 5% to 95% RH with 27°C (80.6°F) maximum dew point
Maximum non-operational altitude 12,000 meters (39,370 feet)
Maximum operational altitude 3,048 meters (10,000 feet)

Maximum vibration Specifications
Operating 0.21 G
rms
at 5 Hz to 500 Hz (all operation orientations)
Storage 1.88 G
rms
at 10 Hz to 500 Hz for 15 minutes
Table 26. Maximum shock pulse specifications
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 Executed shock pulses in z axis (one pulse) of 71 G for up to 2ms
Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any damages to the IT equipment and/or, or both failure from
particulate and gaseous contamination. If the levels of particulate or gaseous pollution exceed the specified limitations and
results in equipment damage or failure, you must rectify the environmental conditions. Remediation of environmental conditions
is the responsibility of the customer.
