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).
You must install the MX960 router in a restricted-access location and ensure the chassisis properly grounded at all times. The MX960 has a two-hole protective grounding terminal provided on the chassis, see Figure 1. Under all circumstances, use this grounding connection to ground the chassis. For AC powered systems, you must also use the grounding wire in the AC power cord along with the two-hole lug grounding connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.
