Expanded operating range
● The operating temperature is specified for a maximum altitude of 950 m for expanded operating range.
● Do not perform cold start at 5°C or lower, due to hard drive constraints.
● Redundant power supplies are required.

Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any damages to the IT equipment and/or 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 may need to rectify the environmental conditions. Remediation of environmental conditions is
the responsibility of the customer.

Air Filtration
Data center air filtration defines that, ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit.
Conductive dust Air must be free of conductive dust, zinc whiskers, or other conductive particles.
● Air must be free of corrosive dust.
Corrosive dust
● Residual dust present in the air must have a deliquescent point less than 60% relative humidity.
