Environmental
Up to 35 °C (95 °F) Maximum temperature is reduced by 1°C/300 m (1°F/547 ft) above 950 m
(3,117 ft).
35 °C to 40 °C (95 °F to
104 °F)
Maximum temperature is reduced by 1°C/175 m (1°F/319 ft) above 950 m
(3,117 ft).
40 °C to 45 °C (104 °F to
113 °F)
Maximum temperature is reduced by 1°C/125 m (1°F/228 ft) above 950 m
(3,117 ft).
Particulate contamination
NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from
particulates and gaseous contamination. If it is determined that levels of particulates or gaseous
pollution are beyond the limits specified below and are the reason for the damage or failures to
your equipment, it maybe necessary for you to re-mediate the environmental conditions that are
causing the damage or failures. Re-mediation of environmental conditions will be the responsibility
of the customer.
Air filtration Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95%
upper confidence limit.
NOTE: 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.
Conductive dust Air must be free of conductive dust, zinc whiskers, or other conductive
particles.
NOTE: Applies to data center and non-data center environments.
Corrosive dust
• Air must be free of corrosive dust.
• Residual dust present in the air must have a deliquescent point less than
60% relative humidity.
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.
