NEBS bonding and grounding stud
If you plan to connect the Cisco CRS-1 4-slot line card chassis system to a network equipment building system (NEBS)-compliant supplemental bonding and grounding system at the site, you must have the following:
•A minimum of one ground lug that has two M6 bolt holes with 0.625-inch (15.86-mm) spacing between them, and a wire receptacle large enough to accept a 6-AWG or larger multistrand copper wire. The lug is similar to the type used for the DC-input power supply leads. This ground lug is not available from Cisco Systems. This type of lug is available from electrical-connector vendors, such as Panduit.
•Two M6 nuts with locking washers (nickel-plated brass is ideal). This hardware is not available from Cisco Systems; they are available from any commercial hardware vendor.
•A commensurately rated ground wire. The actual wire diameter and length depend on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.
