Supplemental Bonding and Grounding Connections
Before you connect power to the router, or power on the router for the first time, we recommend that you
connect the central office ground system or Network Equipment Building System (NEBS) to the
threaded supplemental bonding and grounding receptacles on the router. For more information on
supplemental bonding and grounding cable requirements, see NEBS Supplemental Unit Bonding and
Grounding Guidelines, page1-52.
Table 2 -3 references the grounding receptacle locations for the Cisco ASR 9000 Series Routers.
Table2-3 Grounding Receptacle Locations
Follow these steps to attach a grounding cable lug to the router:
Step1 Insert the grounding screws (10-32 round-head) through the locking washers (ideally nickel-plated
brass) and into the threaded grounding receptacle (has two M6 bolt holes with 0.625 to 0.75 spacing
between them). The wire receptacle is large enough to accept a #6 AWG or larger multi-strand copper
wire.
Step2 Tighten the grounding screws securely to the receptacles.
Step3 Prepare the other end of the grounding wire and connect it to the appropriate grounding point at your
site to ensure an adequate earth ground.
