Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any equipment damage or failure from particulate and gaseous contamination. If
the levels of particulate or gaseous pollution exceed the specified limitations and result in equipment damage or failure, you may need to
rectify the environmental conditions. Remediation of environmental conditions is the responsibility of the customer.

Technical specifications
Specifications
5°C to 40°C at 5% to 85% RH with 29°C dew point.
NOTE:
Outside the standard operating temperature (10°C to
35°C), the system can operate continuously in temperatures as
low as 5°C and as high as 40°C.
For temperatures between 35°C and 40°C, de-rate maximum allowable
temperature by 1°C per 175 m above 950 m (1°F per 319 ft).
–5°C to 45°C at 5% to 90% RH with 29°C dew point.
NOTE:
Outside the standard operating temperature (10°C to
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 between 40°C and 45°C,de-rate maximum allowable
temperature by 1°C per 125 m above 950 m (1°F per 228 ft).
Specifications
Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a
95% upper confidence limit.
NOTE:
The ISO Class 8 condition applies to data center
environments only. This air filtration requirement does not apply
to IT equipment designed to be used outside a data center, in
environments such as an office or factory floor.
