If your rack equipment such as servers, switches and hubs is located in an earthquake zone or is regularly subject to vibration (e.g. an industrial environment), it has greater vulnerability to physical damage and data corruption. Rapid movement or vibration can damage sensitive electronics and affect the data they contain. Racks are designed to keep equipment safe while stationary, but what if the ground isn’t stationary?
A Seismic Rack Enclosure is specifically designed for earthquake zones. It should include a heavy-duty welded steel construction and reinforcing Zone 4 Seismic Brackets for enhanced stability and protection in locations with high levels of vibration. The Seismic Rack Cabinet should also be performance-tested to EIA-310-E, Seismic Zone 4 (NEBS GR-63-CORE) standards to ensure protection of sensitive equipment and data.
How Is It Tested?
The enclosures are loaded with simulated equipment and placed on a shaker table designed to replicate the force of an earthquake. Various configurations and force directions (e.g. side-to-side, front-to-back) are tested to ensure that the heavy-duty steel welding is up to the task. To pass the test, the enclosure must meet displacement* requirements of less than 3 inches and emit no resonant frequency below 6 Hz. A test is considered to be successful if the enclosure’s welding is intact and the equipment within the enclosure is unharmed.
* Displacement refers to the distance the enclosure moves from its initial position during testing.
The SR42UBZ4 Seismic Rack Enclosure is not only designed for earthquake zones, but any environment that experiences excessive vibration. This includes airports, factories, work sites, and other industrial locations.
