The present invention relates to a telecommunications equipment rack with vertical supports on which are located equipment mounting locations, cable troughs for directing cables to and from equipment mounted at the mounting locations, a base to which the vertical supports are mounted, a triangularly shaped gusset reinforcing the connection between the vertical support and the base, and an L-shaped gusset extending between the base and a horizontal bracket mounted to the vertical supports. The vertical supports are made from two U-shaped channels mounted to form a closed rectangular channel. The present invention further relates to a telecommunications equipment rack with vertical supports on which are located equipment mounting locations, cable troughs for directing cables to and from equipment mounted at the mounting locations, a base to which the vertical supports are mounted, and a lower portion of each vertical forming a triangularly shaped gusset reinforcing the connection between the vertical support and the base.

A fiber optic telecommunications bay is provided including modules each including a pivoting panel which selectively closes a portion of the module. Each module has first and second cable access locations. The first cable access location enters the module and allows termination of the cables at the pivoting panel. An opposite side of the pivoting panel allows cables to extend into a second area of the module for storage, and then exiting of the module at a second access location.

A fiber management system for managing fiber optic cables within an enclosure. The fiber management system includes a trough having a plurality of slots for receiving and detachably retaining connectors of the fiber optic cables. A spool is coupled to the trough for coiling the excess length of the fiber optic cables. The trough is fixedly mounted to the inside of the enclosure to allow access to the interior of the enclosure without movement of trough without the fiber optic cables becoming entangled.

A modular uninterruptible power supply is disclosed, which provides complete redundancy for all components required for UPS operation. Novel aspects of the invention include design of the modules and their interconnection and interoperability, as well as improved operation techniques applicable to UPS systems generally.

A slack loop manager is mountable to a network rack having a left side and a right side. The slack loop manager includes a first plurality of slack spools angled from the left side to the right side of the rack, and a second plurality of slack spools angled from the left side to the right side of the rack. The first plurality of slack spools are substantially parallel to the second plurality of slack spools. A divider is positioned between the first plurality and the second plurality of slack spools.
