NEBS grounding point on right of chassis
1
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
Figure 86: Typical DC Power Cable
Lugs, on page 166
).
•
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.
These parts are not available from Cisco (with the exception of the grounding lug), but they are available
from commercial vendors.
Note
Installing the Chassis Ground Cable
This section describes how to install a ground cable to the NEBS bonding and grounding point on the side of
the Cisco NCS 4009 chassis.
Required Tools and Equipment
•
Ground lug and screws (provided in chassis accessory kit)
•
Ground cable
•
Crimping tool and lug specific die
•
3/8-inch drive socket wrench
•
3/8-inch drive torque wrench rated to include 35 in-lb (3.95 N-m).
To ensure a satisfactory ground connection, we recommend 2-4 AWG multistrand copper ground cable. This
cable is not available from Cisco; it is available from any commercial cable vendor such as Panduit. The cable
should be sized according to local and national installation requirements.
