Dell EMC PowerEdge T640 - Particulate and Gaseous Contamination Specifications

Expanded operating temperature Specications
For temperatures between 35°C and 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 maybe reported on the LCD panel and
in the System Event Log.

Particulate and gaseous contamination specications
The following table denes 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 specied 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 ltration Data center air ltration as dened by ISO Class 8 per ISO 14644-1 with a
95% upper condence limit.
NOTE: The ISO Class 8 condition applies to data center
environments only. This air ltration requirement does not apply to
IT equipment designed to be used outside a data center, in
environments such as an oce or factory oor.
