Installing an MX960 Dual-Wide MIC

 

To install a dual-wide MIC (see Figure 2):

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Remove the septum, if necessary (see Figure 1):
    1. Place the MPC on a flat surface (if necessary, remove the MPC from the router as described in Removing an MX960 MPC).
    2. Remove the four screws labeled S on the bottom of the MPC.
    3. Remove the two screws labeled S on the top of the MPC.
    4. Slide the septum towards you and out of the MPC.
    5. Store the septum and screws for later use.
    6. Install the MPC as described in Installing an MX960 MPC.

  3. If the MIC uses fiber-optic cable, verify that a rubber safety cap is over each transceiver on the faceplate. Install a cap if necessary.
  4. Pull the ejector lever above both MIC slots away from the router.
  5. Align the rear of the MIC with the guides located at the corners of the MIC slot.
  6. Slide the MIC into the MIC slot until it is firmly seated in the chassis.Caution

    Slide the MIC straight into the slot to avoid damaging the components on the MIC.

  7. Verify that the ejector levers are engaged by pushing them toward the router.
  8. If the MIC uses fiber-optic cable, remove the rubber safety cap from each transceiver and the end of each 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.

    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 prevents accidental exposure to laser light.

  9. Insert the appropriate cables into the cable connectors on the MIC.
  10. Arrange each cable to prevent the cable 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. 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.

  11. Use one of the following methods to bring the MIC online:
    • Press its online/offline button. Use a narrow-ended tool that fits inside the opening that leads to the button. Press the button until the MIC OK/FAIL LED lights green.

    • Issue the following CLI command:

      user@host> request chassis mic fpc-slot mpc-slot mic-slot mic-slot online

    The normal functioning status LED confirms that the MIC is online. You can also verify correct MIC functioning by issuing the show chassis fpc pic-status command described in Maintaining MX960 MICs.
