Connecting AC Power

The router must be connected to earth ground during normal operation. The protective earthing terminal on the rear of the chassis is provided to connect the router to ground. Additional grounding is provided to an AC-powered router when you plug its power supply into a grounded AC power receptacle.

The AC power cord shipped with the router connects the router to earth ground when plugged into an AC grounding-type power outlet. The router must be connected to earth ground during normal operation.

For power cord requirements, see AC Power, Connection, and Power Cord Specifications.

To connect AC power to the router:

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Use a grounding cable to connect the router to earth ground: (For cable requirements, see Chassis Grounding.)
   1. Verify that a licensed electrician has attached an appropriate grounding cable lug to the grounding cable.
   2. Connect one end of the grounding cable to a proper earth ground, such as the rack in which the router is installed.
   3. With a Phillips screwdriver, remove the screw and washer from the PEM nuts at the grounding point on the rear of the chassis.
   4. Place the grounding lug at the other end of the cable over the grounding point, as shown in Figure 49 through Figure 51.
   5. Secure the cable lug to the grounding point, first with the washer, then with the screw. On J2320 and J2350 routers, use the screw containing a captive washer to secure the cable lug to the grounding point.
3. Locate the power cord or cords shipped with the router, which has a plug appropriate for your geographical location. For power cord specifications, see Power Guidelines, Requirements, and Specifications.
4. For the power supply:
   1. Insert the appliance coupler end of a power cord into the appliance inlet on the power supply faceplate, as shown in Figure 49 through Figure 51.
   2. Insert the plug into an AC power source receptacle.
5. Verify that the power cord does not block access to router components or drape where people can trip on it.
6. On J2320 and J2350 routers, use the power cable tie as follows to relieve strain on the cable (see Figure 49 and Figure 50):
   1. Wrap the loose end of the tie around the cable, and insert it into the opening on the tie.
   2. Pull the end to tighten the tie.

   To release the tie from the cable, press down the tab on the tie and loosen it.
