Maximum vibration
Specifications
Operating
0.26 G
rms
at 5 Hz to 350 Hz (all operation orientations)
Storage
1.88 G
rms
at 10 Hz to 500 Hz for 15 minutes (all six sides tested)
Table 32. Maximum shock pulse specifications
Maximum shock pulse
Specifications
Operating
24 run shock pulses in the positive and negative x, y, and z axis of 6 G for
up to 11 ms. (4 pulse on each side of the system)
Storage
Six consecutively run shock pulses in the positive and negative x, y, and z
axis (one pulse on each side of the system) of 71 G for up to 2 ms.
Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any damages to the IT equipment and/or, or both failure from
particulate and gaseous contamination. If the levels of particulate or gaseous pollution exceed the specified limitations and
results in equipment damage or failure, you must rectify the environmental conditions. Remediation of environmental conditions
is the responsibility of the customer.

Particulate contamination
Specifications
Air filtration
Data center air filtration as defined by ISO Class 8 per ISO
14644-1 with a 95% upper confidence limit.
NOTE:
This condition 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.
NOTE:
Air entering the data center must have MERV11 or
MERV13 filtration.
NOTE:
Air filtering can also be accomplished by filtering
room air with MERV8 filter per ANSI/ASHARE Standard
127.
Conductive dust
Air must be free of conductive dust, zinc whiskers, or other
conductive particles.
