Install the Chassis Ground
Note
The grounding lug and Phillips screws are not available from Cisco Systems. Get the grounding lug from an
electrical-connector vendor and the screws from a hardware vendor. See Page 4 for the parts needed.
Step 1
Locate the chassis ground connector (1) on the rear of your router chassis.
Step 2
Insert the two screws (3) through the holes in the grounding lug (2).
Step 3
Ensure that the grounding lug does not interfere with other router hardware, such as power supplies or the network
processing engine (NPE) or network services engine (NSE).
Step 4
Use the Number 2 Phillips screwdriver to carefully tighten the screws until the grounding lug is held firmly to the
chassis. Do not overtighten the screws.
Step 5
Use the wire stripper to strip one end of the 6-AWG wire approximately 0.75 inches (19.05 mm).
Step 6
Insert the 6-AWG wire (4) into the wire receptacle on the grounding lug.
Step 7
Use the crimping tool to carefully crimp the wire receptacle around the wire; this step is required to ensure a proper
mechanical connection.
Step 8
Connect the opposite end of the grounding wire to the appropriate grounding point at your site to ensure an adequate
chassis ground.
