Expanded operating temperature

Table 31. Expanded operating temperature specifications

Expanded operating temperature

Continuous operation

≤ 1% of annual operating hours

NOTE:

When operating in the expanded temperature range, system performance may be impacted.

NOTE:

When operating in the expanded temperature range, ambient temperature warnings may be reported on the LCD

panel and in the System Event Log.

Expanded operating temperature restrictions

● Do not perform cold start below -15C Per IEC 60945.

● The operating temperature specified is for a maximum altitude of 950 m.

● Redundant power supplies are required.

● Non-Dell qualified peripheral cards and/or peripheral cards greater than 25 W are not supported.

Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any equipment damage 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. Re-mediation of environmental conditions is the responsibility

of the customer.

Technical specifications

Specifications

5°C to 45°C at 5% to 85% RH with 29°C dew point.

NOTE:

Outside the standard operating temperature (10°C to

35°C), the system can operate continuously in temperatures as low

as 5°C and as high as 45°C.

For temperatures between 35°C and 45°C, de-rate maximum

allowable temperature by 1°C per 175 m above 950 m (1°F per 319

ft).

–5°C to 55°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 55°C for a

maximum of 1% of its annual operating hours.

For temperatures between 45°C and 55°C, de-rate maximum

allowable temperature by 1°C per 125 m above 950 m (1°F per 228

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.

Air must be free of conductive dust, zinc whiskers, or other

conductive particles.

NOTE:

This condition applies to data center and non-data center

environments.
