Maximum shock pulse specifications Maximum shock pulse Specifications Operating Six consecutively executed shock pulses in the positive and negative x, y, and z axis of 6 G for up to 11 ms. Six consecutively executed shock pulses in the positive and negative x, y, and z axis of 6G for up to 11ms. 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 prevent the damage 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. 10 Technical specifications

Particulate and gaseous contamination specifications
The following table defines the limitations that prevent the damage 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.
