Determine whether the equipment will be deployed in a carrier central office, enterprise data hall, edge shelter, or outdoor enclosure. Identify the local seismic zone and the ASHRAE environmental class the facility operates within.

The seismic test requires securing the equipment to a shaker table and subjecting it to a series of synthesized waveforms representing a Zone 4 earthquake (the most severe zone). The equipment must remain functional before, during, and after the test, with no structural failures or component displacements. 4. The NEBS Compliance Process
