Optional seismic support for 700 series racks

With the addition of optional seismic support, the SBK-700 Series racks can be certified to Telcordia NEBS (Network Equipment Building Systems) standard GR-63-CORE. When properly installed, the 700 Series racks successfully withstood rigorous real-world dynamic testing: the racks are capable of withstanding up to a Zone 4 earthquake, comparable to a magnitude of 8.0 on the Richter scale!
