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

10% to 80% Relative Humidity with 26°C (78.8°F)
maximum dew point.
5% to 95% RH with 33°C (91°F) maximum dew
point. Atmosphere must be non-condensing at all
times.
0.26 G at 5 Hz to 350 Hz (all operation
rms
orientations).
1.87 G at 10 Hz to 500 Hz for 15 min (all six
rms
sides tested).
One shock pulse in the positive z axis of 40 G for
2.3 ms in all operational orientations.
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.
3048 m (10,000 ft).
12,000 m (39,370 ft).
Maximum temperature is reduced by 1°C/300 m
(1°F/547 ft) above 950 m (3,117 ft).
Maximum temperature is reduced by 1°C/175 m
(1°F/319 ft) above 950 m (3,117 ft).
Maximum temperature is reduced by 1°C/125 m
(1°F/228 ft) above 950 m (3,117 ft).
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.
