Bonding and Grounding Guidelines

Caution
The chassis might have more than one power connection. All connections must be removed to de-energize
the chassis. Statement 1028
Bonding and Grounding Guidelines
The router chassis has a safety earth ground connection in conjunction with power cabling to the fixed
configuration power shelves. The chassis allows you to connect the central office ground system or interior
equipment grounding system to the bonding and grounding receptacles on the router chassis, when either a
fixed or modular configuration power system is installed. Two threaded ground inserts are located on top of
the chassis rear (MSC) side panel to the left of the lower power shelf. The following figure shows the NEBS
and grounding points on the rear (MSC) side of the chassis with a modular configuration DC power shelf
installed. This grounding point is also referred to as the network equipment building system (NEBS) bonding
and grounding stud. The location of the grounding points on the LCC is the same for both fixed and modular
configuration power systems.
Note
These bonding and grounding receptacles are provided to satisfy the Telcordia NEBS requirements for bonding
and grounding connections.
