  2. Connect the ground cable.
    1. Use a Phillips screwdriver to remove the M4 screw from the ground point on the rear panel of the router. Keep the M4 screw in an appropriate place for later use.
    2. Align the M4 lug of the ground cable with the tapped hole on the ground point, and then secure the ground cable with the M4 screw, Tighten the M4 screw with a torque of 1.4 N•m.
    3. Connect the M6 lug of the ground cable to a ground point on the cabinet, Tighten the M6 screw with a torque of 4.8 N•m.

Follow-up Procedure
