Seismic-Certified Racks Provide Maximum Durability Racks :: A Requirement for Zone 4 Regions, Also Beneficial in Many Other Environments Network engineers deploying equipment in Zone 3 or Zone 4 rated geographical areas have a simple choice to make when specifying equipment racks: put simply, they must use seismic-certified racks in all installations. However, many other applications benefit from the design strength of seismic-certified racks. Stronger welds and heavier-duty metals are just two of the factors that enhance the strength and durability of seismic racks. In addition, the general design and construction of a seismic rack provides greater stability for heavier equipment, helping to ensure long-term perform- ance of deployed equipment. Certification is Key

Table 1: Size and configuration options for Telect seismic- certified equipment racks.
Telect offers a full range of seismic-certified equipment racks, in a comprehensive array of configurations.
Unequal Flange Racks The standard for most telecom networks, unequal flange racks feature a design that includes built-in cable management due to the extension of flanges on the frame posts. Like network bays, unequal flange racks are available in the widest range of configurations; for virtually any specification, there’s an unequal flange rack that will fit perfectly.
Each Telect seismic rack is independently certified to Zone 4 requirements. Different types of racks are engineered to handle varying weights of equipment (see Table 2 below for details). When a rack specification is not pre-determined for an application, using the weight certification is a simple way to determine the appropriate rack for the installation.
Telect’s line of seismic-certified racks — which includes the full range of Hendry equipment racks — is one of the most comprehensive available today.
Seismic Indoor Cabinets For applications requiring additional security for mounted equipment, a seismic-certified cabinet is an excellent choice. Lockable doors, adjustable mounting rails and pivoting surfaces provide enhanced functionality in Telect cabinets, which are available in 19” and 23” widths.
Network Bays Widely used in telecommunications central offices, network bays provide a basic frame for equipment housing. Guard boxes support externally mounted electrical strips. Network bays are available in a comprehensive range of configurations to meet nearly any specification.
Global Seismic Frames Global seismic frames meet the requirements of mission- critical applications worldwide. Combining a robust physi- cal design with detailed features that address the equip- ment requirements of different global markets, these innovative frames are available in North American and ETSI-standard configurations.

Seismic-Certified Racks Provide Maximum Durability Racks :: A Requirement for Zone 4 Regions, Also Beneficial in Many Other Environments Conclusion
Heavy-Duty Battery Racks FCC Requirements for backup power in communications networks have made battery backup solutions a key application. Telect heavy-duty battery racks are the most robust two-post system available today. Available in -48V and +24V configurations, these racks support up to five battery shelves (typically four batteries per shelf) for a high-density, highly durable solution.
The equipment rack is the foundation upon which nearly all communications equipment deployments must be built. Choosing a seismic-certified equipment rack helps to make that foundation as solid as possible. Oftentimes the rack is a low purchase priority compared to more costly equipment that will eventually be installed in it; however, selecting the right rack for the application is a key step in ensuring ongoing performance.
Furthermore, this unique rack can also accommodate equipment other than batteries, providing one of the most versatile and heavy-duty general use seismic-certified equipment rack solutions available today.
A seismic-certified equipment rack from Telect is the strongest way to start each installation, whether you’re in a Zone 3 or Zone 4 area, or are just looking for a higher level of strength and durability.
Accessories and Hardware From seismic anchor kits to cable management, Telect provides all of the accessories required to complete the installation of a seismic-certified equipment rack. All accessories (and all rack configurations) are available online at Telect.com.
