Replacing a Cable on an MX960 DPC, MPC, MIC, or PIC

Removing a Cable on an MX960 DPC, MPC, MIC, or PIC

Removing and installing cables on a DPC, MPC, MIC, or PIC does not affect router function, except that the component does not receive or transmit data while its cable is disconnected.

To remove a fiber-optic cable:

  1. If the component connects to fiber-optic cable, have ready a rubber safety cap for each cable and transceiver.
  2. If removing all cables connected to the component, use one of the following methods to take the component offline:

    • To take a DPC or an MPC offline:

      • Press and hold the corresponding online button on the craft interface. The green OK LED next to the button begins to blink. Hold the button down until the LED goes off.

      • Issue the following CLI command:

        For more information about the command, see the CLI Explorer.

    • To take a PIC offline:

      • Press the online/offline button on the PIC. For a PIC installed in an FPC3, use a narrow-ended tool that fits inside the opening that leads to the button. Press and hold the button until the PIC LED goes out (about 5 seconds).

      • Issue the following CLI command:

        For more information about the command, see the CLI Explorer.

    • To take a MIC offline:

      • Press the online/offline button on the MIC. Use a narrow-ended tool that fits inside the opening that leads to the button. Press and hold the button until the MIC LED goes off (about 5 seconds).

      • Issue the following CLI command:

        For more information about the command, see the CLI Explorer.

  3. Unplug the cable from the cable connector port. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.
    Laser Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered, except when you are inserting or removing cable. The safety cap keeps the port clean and protects your eyes from accidental exposure to laser light.

  4. Remove the cable from the cable manager and detach it from the destination port.

Installing a Cable on an MX960 DPC, MPC, MIC, or PIC

To install a cable:

  1. Have ready a length of the type of cable used by the component. For cable specifications, see the MX Series Interface Module Reference.
  2. If the cable connector port is covered by a rubber safety cap, remove the cap.
    Laser Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered, except when you are inserting or removing cable. The safety cap keeps the port clean and protects your eyes from accidental exposure to laser light.

  3. Insert the cable connector into the cable connector port on the component faceplate.
  4. Arrange the cable in the standard or extended cable manager to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on the loop helps to maintain its shape.
    CAUTION:

    Avoid bending a fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

    CAUTION:

    Do not let fiber-optic cables hang free from the connector. Do not allow the fastened loops of a cable to dangle, which stresses the cable at the fastening point.

  5. Insert the other end of the cable into the destination port.
  6. Repeat the previous steps for any additional cables.
  7. If the component is offline (its failure indicator LED is lit), use one of the following methods to bring it online.

    • To bring a DPC or MPC online:

      • Press and hold the corresponding online button on the craft interface until the green OK LED next to the button lights steadily, in about 5 seconds.

      • Issue the following CLI command:

        For more information about the command, see the CLI Explorer.

    • To bring a PIC online:

      • Press the PIC offline/online button until the PIC LED lights green. For a PIC installed in FPC3, use a narrow-ended tool that fits inside the opening that leads to the button.

      • Issue the following CLI command:

        For more information about the command, see the CLI Explorer.

    • To bring a MIC online:

      • Press the MIC offline/online button until the MIC LED lights green.

      • Issue the following CLI command:

        For more information about the command, see the CLI Explorer.

    The normal functioning indicator LED confirms that the component is online. You can also verify correct DPC or MPC functioning by issuing the show chassis fpc command or the correct PIC or MIC functioning by issuing the show chassis fpc pic-status command.
