Allowable operations
Maximum temperature gradient (applies to both operation and
non-operation)
20°C in an hour* (36°F in an hour) and 5°C in 15 minutes (9°F in
15 minutes), 5°C in an hour* (9°F in an hour) for tape hardware
Non-operational temperature limits -40 to 65°C (-40 to 149°F)
Non-operational humidity limits 5% to 95% RH with 27°C (80.6°F) maximum dew point
Maximum non-operational altitude 12,000 meters (39,370 feet)
Maximum operational altitude 3,048 meters (10,000 feet)
*: Per ASHRAE thermal guidelines, these are not instantaneous rates of temperature change.

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 64. Maximum shock pulse specifications
Maximum shock pulse Specifications
Operating 24 executed 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 executed 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.
