SEISMIC APPLICATIONS
Solutions adapted to enclose and protect technological systems against seismic adversity
- Racks and enclosures constructed with superior strength and rigidity to protect operating and communication equipment in the event of an earthquake, or where vibration and other motion is present.
- The use of seismic solutions is not only recommended in areas where ground motion risk is present, but also where critical equipment is subjected to vibration and other motion which may over-stress equipment framework, components, and connections.
- Power plants, railroads, and airports are application examples where movement or vibration unrelated to seismic activity are present.
- Industry standards, requirements, and compliance for racks and enclosures: Telcordia GR-63-CORE Network Equipment Building System (NEBS™), California Building Code (CBC), International Building Code (IBC), Office of Statewide Health Planning and Development (OSHPD) building approval with pre-approval of Manufacturer’s Certification (OPM), IEC 61587

RACKS & CABINETS
Seismic 2-Post Open Frame Rack
Designed for applications affected by vibrations and seismic activity, Seismic 2-Post Open Frame Racks integrate cable management into a fully welded, heavy gauge steel frame. Used in communication data center and telecommunication room applications, racks can be ganged with standard 2- or 4-post racks to expand existing systems.
Seismic 4-Post Open-Frame Rack
Seismic 4-Post Open Frame Racks combine the mounting security of a cabinet with the accessibility of a rack. Used in communication data center and telecommunication room applications that are subject to seismic activity or vibration, these adjustable-depth racks support deeper, heavier network equipment and can be ganged with standard 2-post or other 4-post racks to expand existing systems.
