Table 19. Expanded operating temperature specifications(continued) Expanded operating temperature Specifications NOTE: Outside the standard operating temperature (10°C-35°C), the system can operate continuously in temperatures as low as 5°C and as high as 40°C. 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 specified is for a maximum altitude of 950 m for Fresh Air cooling. • Two redundant power supply units are required. • Cooling redundancy is not supported due to single fan only in system. • Support up to 80 W processor. • One system fan is required. • Non-Dell qualified peripheral cards and/or peripheral cards greater than 25 W are not supported. • GPU is not supported. • Tape backup unit is supported. 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. Table 20. Particulate contamination specifications Particulate contamination Air filtration Specifications Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit. NOTE: This condition applies to data center environments only. Air filtration requirements do not apply to IT equipment designed to be used outside a data center, in environments such as an office or factory floor. NOTE: Air entering the data center must have MERV11 or MERV13 filtration. 16 Technical specifications

Specifications
NOTE:
Outside the standard operating temperature
(10°C–35°C), the system can operate continuously in
temperatures as low as 5°C and as high as 40°C.
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
