Expanded operating temperature
Specifications
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.

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.
