CiscoXR 12406 Router Installation Guide

OL-13831-01

•On Cisco XR 12406 routers configured for DC-input operation, the DC PD U

is equipped with a DC power connector block 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.

Note The Cisco XR 12406 router grounding architecture conform s to the DC-I

(DC-isolated) method of grounding as described in Telcordia

GR-1089-CORE. A DC-I architecture means that there is no connection

between the DC return terminal and the frame ground. D C return and

frame ground are isolated from one another at the router.

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 rou ter chassis. This

grounding point consists of threaded inserts is located on the side of the chassis

near the back of the chassis (Figure3-4). 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 connecti ons.
