Environmental
Maximum Shock
Operating One shock pulse (one pulse each side of the system) of 31 G for 2.6 ms in
the operational orientation.
Non-operating 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 ms.
Six consecutively executed shock pulses in the positive and negative x, y,
and z axes (one pulse on each side of the system) of 32 G faired square
wave pulse with velocity change at 270 inches/second (686 centimeters/
second).
Altitude
Operating
–16 m to 3048 m (10,000 ft).
NOTE: For altitudes above 950 m (3,117 ft), the maximum operating
temperature is derated 1°C/300 m (1 ºF/547 ft).
Storage –15.2 m to 12,000 m (–50 ft to 39,370 ft)
Airborne Contaminant Level
Class G1 as defined by ISA-S71.04-1985
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.
