Relative humidity
Storage 5% to 95% RH with 33°C (91 °F) maximum dew point.
Atmosphere must be non-condensing always.
Operating 10% to 80% Relative Humidity with 29°C (84.2°F) maximum
dew point.
Maximum vibration
Operating 0.26 G
rms

Storage 1.87 G
rms
at 10 Hz to 500 Hz for 15 min (all six sides tested).
Maximum shock
Operating Six consecutively executed shock pulses in the positive and
negative x, y, and z axes of 40 G for up to 2.3 ms.
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 ms.

above 950 m (3,117 ft).
Particulate contamination
註
: 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
註
: 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 percent upper confidence limit.
註
: Air entering the data center must have MERV11 or
MERV13 filtration.
Conductive dust
註
: Applies to data center and non-data center
environments.
Air must be free from conductive dust, zinc whiskers, or other
conductive particles.
