Dell EMC PowerEdge T140 - Particulate and Gaseous Contamination Specifications

Expanded operating temperature Specications
For temperatures 35°C– 40°C, derate maximum allowable
temperature by 1°C per 175 m (1°F per 319 ft) above 950 m (3,1171
ft).
≤ 1% of annual operating hours -5°C–45°C at 5% to 90% RH with 29°C dew point.
NOTE: Outside the standard operating temperature
(10°C–35°C), the system can operate down to -5°C or
up to 45°C for a maximum of 1% of its annual operating
hours.
For temperatures 40°C– 45°C, derate maximum allowable
temperature by 1°C per 125 m (1°F per 228 ft) above 950 m (3.117
ft).
NOTE: When operating in the expanded temperature range, the performance of the system may be impacted.
NOTE: When operating in the expanded temperature range, ambient temperature warnings may be reported on the System
Event Log.
Expanded operating temperature restrictions
• Do not perform a cold startup of the system below 5°C.
• The operating temperature specied is for a maximum altitude of 3048 m (10,000 ft).
• One non-redundant power supply unit is required.
• One system fan required.
• Non-Dell qualied peripheral cards and/or peripheral cards greater than 25 W are not supported.
• GPU is not supported.
• Tape backup unit is not supported.
• For a system with 4 TB (or more) drive capacity, PERC is required for thermal control.

Particulate and gaseous contamination specications
The following table denes 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 specied limitations and results in equipment damage or
failure, you must rectify the environmental conditions. Remediation of environmental conditions is the responsibility of the customer.
