Maximum Shock
Operating One shock pulse in the positive z axis (one pulse on each
side of the system) of 31 G for 2.6 ms in the operational
orientation.
Storage Four consecutively executed shock pulses in the positive
and negative y and z axes (one pulse on each side of the
system) of 71 G for up to 2 ms.

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 Air must be free of conductive dust, zinc whiskers, or
other conductive particles.
