Environmental
NOTE: Applies to data center and non-data center environments.
Gaseous contamination
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Copper coupon
corrosion rate
<300 Å/month per ClassG1 as defined by ANSI/ISA71.04-1985.
Silver coupon corrosion
rate
<200 Å/month as defined by AHSRAE TC9.9.
Expanded operating temperature
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 and in the system event log.
Continuous operation
5°C to 40°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 down to 5°C or as high
as 40°C.
For temperatures between 35°C and 40°C, de-rate
maximum allowable temperature by 1°C per 175m
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).
Expanded operating temperature restrictions
• Do not perform a cold startup below 5°C.
• The operating temperature specified is for a
maximum altitude of 3050 m (10,000 ft).
• Redundant power supplies are required.
• Peripheral cards that are not Dell-qualified are
not supported.
