Grounding the MX960 Router
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis
grounding points using two screws. You must provide the grounding cables (the cable lugs are supplied
with the router).
1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding
cable.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
an approved site ESD grounding point. See the instructions for your site.
3. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections
are made.
4. Connect the grounding cable to a proper earth ground.
5. Detach the ESD grounding strap from the site ESD grounding point.
6. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
