CPI’s Seismic Frame® Two-Post Rack reduces the risk of equipment damage during an earthquake by resisting the swaying motion and reducing the vibration transferred through the rack to equipment, which means faster network recovery. The rack is rated for a 1,000 lb (453.6 kg) seismic Zone 4 load per Section 4.4 of the Telcordia® Technologies, Inc. GR-63-CORE Network Equipment Building Systems (NEBS) requirements. |

- Welded steel rack is engineered specifically to protect valuable network equipment in areas with seismic activity
- Independent seismic testing and certification ensures the rack meets industry-recognized requirements
- Seismic load rating of 1,000 lb (453.6 kg)
- The rack is available in both 19” EIA-310-D and 23” widths to support a variety of equipment such as patch panels and network switches
- Two styles of mounting rails, #12-24 threaded or square-punched adjustable-depth, further increase application possibilities
- Mounting rails are marked and numbered to simplify equipment installation; RMU numbering can start at the top or bottom of the rack
- Each 19” wide rack fits within a 24” (610 mm) raised access floor tile for uniform installation
- Fully bonded rack has two masked grounding locations and includes a Two Mounting Hole Ground Terminal Block for easy connection to the Telecommunications Grounding Busbar
- Built-in mounting locations for Vertical Power Strips and T-shaped Cable Management Fingers to provide power and cable distribution for equipment
- UL Listed

Telecordia Technologies GR-63-CORE NEBS standard defines the standard industry seismic test for equipment racks and cabinets. During seismic testing the rack or cabinet is attached to a concrete slab, loaded with weight and then the rack or cabinet, weight and slab are subjected to a shaker test where a random waveform of a certain intensity moves the rack in a front-to-back, side-to-side, and up-down motion to simulate an earthquake. Movement at the top of the rack (deflection) is measured and compared to the base movement which follows input wave form. The GR-63-CORE requirements define deflection limits and other requirements. If the rack exceeds the limits of the test, the weight must be reduced or the design must be stiffened.
Seismic Frame® Two-Post Rack was independently tested in four configurations (19” wide with 6” deep rails; 19” wide with 3” deep rails; 23” wide with 6” deep rails; and 23” wide with 3” deep rails) while loaded with 1,000 lb (453.6 kg) of weight to simulate equipment and passed all GR-63-CORE NEBS Zone 4 requirements and objectives. The racks were not damaged during testing. NEBS Zone 4 seismic testing is the most intense NEBS test and simulates a severe Richter Magnitude 7.0 – 8.3 earthquake. The video shows clips from the tests of the 19” wide rack with 6” deep rails. Note the minimal movement at the top of the rack.
