Network Equipment – Earthquake Resistance
|Publication Date:||1 June 2008|
This standard, when used with established earthquake qualification practices, sets forth test methods, performance requirements, and acceptance criteria for determining the earthquake resistance of telecommunications equipment. Earthquake resistance is the equipment's ability to maintain a defined level of functionality without physical damage, disruption of service, or personnel hazard, during and after an earthquake.
Unless specifically indicated, this standard does not include performance requirements for the equipment mounting hardware, such as concrete anchor bolts. It is expected that the mounting hardware used at the installation will be sufficient to withstand earthquake loads.
The purpose of this standard is to establish minimum levels of robustness for telecommunications equipment that may provide a level of survivability to preserve telecommunications services during and after an earthquake. This standard establishes methods for determining equipment functionality within a defined earthquake environment.
The test processes and performance requirements described in this standard apply to all telecommunications equipment fastened to the floor, walls, or other structural elements of telecommunications infrastructure.
Examples of telecommunications equipment are switching equipment, transmission equipment, dc power systems, network/operation support, and data equipment.
Equipment may be tested to either of two earthquake risk levels, low risk or high risk, as specified. Equipment (mounted in a frame or cabinet) tested and found compliant for the high risk level requirements is considered compliant with the low risk level requirements. No additional testing is necessary.
