Table 28 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 LCD panel and in 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 particulates and gaseous contamination. If the levels of particulates or
gaseous pollution exceed the specified limitations and result in equipment damage or failure, you
must rectify the environmental conditions. Remediation of environmental conditions is the
responsibility of the customer.
Air filtration specification: Data center air filtration as defined by ISO Class 8 per ISO 14644-1
should have a 95% upper confidence limit. Note: This condition applies only to data center
environments. 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. Conductive dust specification: Air must be free of
conductive dust, zinc whiskers, or other conductive particles. Note: This condition applies to data
center and nondata center environments. Corrosive dust specification: Air must be free of
corrosive dust. Residual dust present in the air must have a deliquescent point less than 60%
relative humidity. Note: This condition applies to data center and non-data center environments.
