Perform the following procedure to ground the Cisco ASR 903 Router using a 2-hole lug and the corresponding
mounting point. Most carriers require a minimum 6 AWG ground connection. Verify your carrier’s requirements
for the ground connection.
Step 1
If your ground wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5 inch ± 0.02 inch (12.7 mm ±0.5
mm) ( as shown in the figure below).

Step 2
Slide the open end of your 2-hole ground lug over the exposed area of the ground wire.
Step 3
Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground wire as shown
in the figure below.

Step 4
Use a Phillips head screwdriver to attach the 2-hole ground lug and wire assembly to the router with the 2 pan-head
Phillips head screws. For a 19-inch EIA rack, attach the 2-hole ground lug to the rear of the router.
Step 5
Connect the other end of the ground wire to a suitable grounding point at your site.
