Cisco Systems OL-11497-03 manual Supplemental Bonding and Grounding Port for Nebs Compliance

Chapter 2 Preparing for Installation

Site Requirement Guidelines

•On Cisco 12006 and Cisco 12406 Routers configured for DC-input operation, the DC PDU is equipped with two DC power connector blocks, each with wire-connection terminals for connecting the negative lead (top terminal), the positive lead (middle terminal), and the ground lead (bottom terminal). This is a safety feature.

If the router is installed in a NEBS environment, we strongly recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding point on the router chassis. This grounding point consists of three threaded inserts is located on the side of the chassis near the back of the chassis. (See Figure 2-4.) It is also referred to as the NEBS bonding and grounding receptacle, and is intended to satisfy the Telcordia NEBS requirements for supplemental bonding and grounding connections.
