Installing the Chassis Ground
Perform the following procedure to ground the Cisco ASR 903 Router as a satellite shelf 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.
SUMMARY STEPS
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).
2. Slide the open end of your 2-hole ground lug over the exposed area of the ground wire.
3. Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground
wire as shown in this figure.
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.
5. Connect the other end of the ground wire to a suitable grounding point at your site.
