Installing an MX960 MPC

 

An MPC installs vertically in the front of the router. The MPCs are hot-insertable and hot-removable. A fully configured MPC can weigh up to 18.35 lb (8.3 kg). Be prepared to accept its full weight.

To install an MPC (see Figure 1):

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Place the MPC on an antistatic mat.
  3. Take each MIC to be installed in the replacement MPC out of its electrostatic bag, and identify the slot on the MPC where it will be connected.
  4. Verify that each fiber-optic MIC has a rubber safety cap covering the MIC transceiver. If it does not, cover the transceiver with a safety cap.
  5. Install each MIC into the appropriate slot on the MPC.
  6. Locate the slot in the card cage in which you plan to install the MPC.
  7. Orient the MPC so that the faceplate faces you.
  8. Lift the MPC into place, and carefully align the sides of the MPC with the guides inside the card cage.Caution

    When the MPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

  9. Slide the MPC all the way into the card cage until you feel resistance.
  10. Grasp both ejector handles, and rotate them clockwise simultaneously until the MPC is fully seated.
  11. If any of the MICs on the MPC connect to fiber-optic cable, remove the rubber safety cap from each transceiver and cable.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.

  12. Insert the appropriate cable into the cable connector ports on each MIC on the MPC. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a loop helps to maintain its shape.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.

    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.

  13. Use one of the following methods to bring the MPC online:
    • Press and hold the corresponding MPC online button on the craft interface until the green OK/FAIL LED next to the button lights steadily, in about 5 seconds.

    • Issue the following CLI command:

      user@host>request chassis fpc slot slot-number online

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

    Caution

    After the OK/FAIL LED lights steadily, wait at least 30 seconds before removing the MPC again, removing an MPC from a different slot, or inserting an MPC in a different slot.

You can also verify correct MPC and MIC functioning by issuing the show chassis fpc and show chassis fpc pic-status commands described in Maintaining MX960 MPCs and Maintaining MX960 MICs.
