Environmental
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 and/or failures to your equipment, it may be necessary for you
to re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation of
environmental conditions will be the responsibility of the customer.
Air Filtration
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.
Data center air filtration as defined by ISO Class 8 per
ISO 14644-1 with a 95% upper confidence limit.
NOTE: Air entering the data center must have
MERV11 or MERV13 filtration.
Conductive Dust
NOTE: Applies to data center and non-data center
environments.
Air must be free of conductive dust, zinc whiskers, or
other conductive particles.
Corrosive Dust
NOTE: Applies to data center and non-data center
environments.
• Air must be free of corrosive dust.
• Residual dust present in the air must have a
deliquescent point less than 60% relative humidity.
Gaseous Contamination
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Copper Coupon Corrosion Rate <300 Å/month per Class G1 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.
< 10% of annual operating hours 5 °C to 40 °C at 5% to 85% RH with 26 °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 40 °C for a maximum of 10% of its annual
operating hours.
For temperatures between 35 °C and 40 °C, de-rate
maximum allowable dry bulb 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 26 °C dew point.
