Disconnecting an MX960 AC Power Supply Cord

1. Move the AC input switch, which is to the right of the appliance inlet on the chassis, to the off (O) position.
2. Unplug the power cord from the power source receptacle.
3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
4. Unplug the power cord from the appliance inlet on the power supply.

Connecting an MX960 AC Power Supply Cord

1. Locate a replacement power cord with the type of plug appropriate for your geographical location (see AC Power Cord Specifications for the MX960 Router).
2. Plug the replacement power cord into the corresponding appliance inlet located in the chassis directly above the power supply.
3. Insert the power cord plug into an external AC power source receptacle.

   Note: Each power supply must be connected to a dedicated AC power feed and a dedicated customer site circuit breaker. We recommend that you use a 15 A (250 VAC) minimum, or as required by local code.

4. Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and access to router components, or drape where people could trip on it.
5. Move the AC input switch in the chassis above the power supply to the on (—)position and observe the status LEDs on the power supply faceplate. If the power supply is correctly installed and functioning normally, the AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit.
