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.
