Installing the Chassis Ground Cable
To ensure a satisfactory supplemental ground connection to the chassis, use the following parts:
•
One grounding lug, which has two M6 bolt holes with 0.625- to 0.75-inch (15.86- to 19.05-mm)
spacing between them, and a wire receptacle able to accept a 2-4-AWG or larger, multistrand copper
wire. This lug is similar to those used for the DC input power supply leads (see
•
Two M6 round-head screws and two locking washers (nickel-plated brass is ideal).
•
One grounding wire. Although we recommend at least 2-4-AWG multistrand copper wire, the wire
diameter and length depend on your chassis location and site environment.
Note
These parts are not available from Cisco (with the exception of the grounding lug), but they are available
from commercial vendors.
