Table 34. Expanded operating temperature specifications
Expanded operating temperature
Specifications
Continuous operation
5°C–40°C at 5% to 85% RH with 29°C dew point.
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.

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.

Particulate contamination
Specifications
Air filtration
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.
