Replacing an MX960 AC Power Supply Cord

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. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to an ESD point.
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 and High-Voltage Second-Generation Universal (MX960-PSM-HV) 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.

   For enhanced power supplies, also plug the replacement power cord into the corresponding power supply inlet.

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.

   Note

   For the high-capacity second-generation AC power supply, use a screwdriver to tighten the screw on the AC receptacle retainer to prevent the AC power cord from getting lose.

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.
