NEBS Supplemental Unit Bonding and Grounding Guidelines
You must permanently connect the central office ground system or interior equipment grounding system to
the supplemental bonding and grounding connection on the side of the router chassis to meet network equipment
building system (NEBS) requirements as well as safety compliance requirements. These grounding points are
referred to as the NEBS bonding and grounding points.
These bonding and grounding connections satisfy the Telcordia NEBS requirements for supplemental bonding
and grounding connections. For an AC powered router, if you are not installing the router in a NEBS
environment, you can choose to bypass these guidelines and rely on the safety earth ground connections to
the AC power modules.

The following figures show the NEBS grounding locations for the Cisco ASR 9901 Router and Cisco ASR
