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

Technical specifications
Specifications
up to 45°C for a maximum of 1% of its annual operating
hours.
For temperatures 40°C– 45°C, derate maximum allowable
temperature by 1°C per 125 m (1°F per 228 ft) above 950 m (3.117
ft).
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 MERV11
or MERV13 filtration.
