Grounding the Cisco 10720 Internet Router

If the router is installed in a Network Equipment Building System (NEBS) environment, follow the
guidelines in this section. For installations other than in a NEBS environment, you may chose to rely on
the safety earth ground connection supplied via the International Electrotechnical Commission
(IEC) 320 plugs for the AC power supply and DC power supply.
For additional NEBS information, see the
10720

Supplemental Unit Bonding and Grounding Guidelines

If the router is not installed in a NEBS environment, you can bypass these guidelines and rely on the
safety earth ground connection supplied via the IEC 320 plugs for the AC power supply and DC power
supply.
Bonding and grounding receptacles are intended to satisfy the Telcordia NEBS requirements for
supplemental bonding and grounding connections. The router requires a safety earth ground connection
as part of the power cabling to the AC and DC power supplies.
We strongly recommend that you connect the central office (CO) ground system or interior equipment
grounding system to the chassis. Grounding to the CO system or your interior equipment grounding
system meets the NEBS bonding and grounding requirement.
