Expanded operating temperature
Specifications
For temperatures between 35°C to 40°C, de-rate maximum allowable
temperature by 1°C per 175 m above 950 m (1°F per 319 ft).
≤ 1% of annual operating hours
–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).
NOTE:
When operating in the expanded temperature range, system performance may be impacted.
NOTE:
When operating in the expanded temperature range, ambient temperature warnings may be reported in the System Event
Log.

Particulate and gaseous contamination specifications
This section 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.
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:
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.
NOTE:
Air entering the data center must have MERV11 or MERV13
filtration.
Conductive dust
Air must be free of conductive dust, zinc whiskers, or other conductive
particles.
NOTE:
This condition applies to data center and non-data center
environments.
Corrosive dust
•
Air must be free of corrosive dust.
•
Residual dust present in the air must have a deliquescent point less than
60% relative humidity.
