Bonding and Grounding Guidelines

The router chassis has safety earth ground connections in conjunction with the power cabling to the fixed configuration PDUs. Modular configuration power supports chassis grounding only. The chassis allows you to connect the central office ground system or interior equipment ground system to the bonding and grounding receptacles on the router chassis, when either a fixed or modular configuration power system is installed. Six chassis grounding points are provided at the rear (MSC) side of the chassis, as shown in Figure 2-1. Each side of the chassis has one pair of threaded ground studs located on the inside of the chassis and two sets of grounding receptacles located on the outside of the chassis. These ground points are also called the network equipment building system (NEBS) bonding and grounding points.

Note These bonding and grounding receptacles satisfy the Telcordia NEBS requirements for bonding and grounding connections.
