Ambient temperature limitations
The following table lists configurations that require ambient temperature less than 35°C.
NOTE: The ambient temperature limit must be adhered to ensure proper cooling and to avoid excess processor
throttling, which may impact system performance.

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.

Specifications
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 the MERV11 or
MERV13 filtration.
