Environmental
Storage Six consecutively executed shock pulses in the positive and
negative x, y, and z axes (one pulse on each side of the system)
of 71 G for up to 2 m.
Altitude
Operating –30.5 m to 3048 m (–50 to 10,000 ft).
NOTE: For altitudes above 2950 ft, the maximum operating
temperature is derated 1.8 ºF/1000 ft.
Storage Up to 12,000 m ( 39,370 ft).
Operating Altitude De-rating 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 and/or failures to your equipment it may be necessary for you
to remediate the environmental conditions that are causing the damage and/or failures. Remediation 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.
