Installing an MX960 PIC

 

To install a PIC (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. If the PIC uses fiber-optic cable, verify that a rubber safety cap is over each transceiver on the faceplate. Install a cap if necessary.
  3. Align the notches in the connector at the rear of the PIC with the notches in the PIC slot in the FPC and then slide the PIC in until it lodges firmly in the FPC.Caution

    Slide the PIC straight into the slot to avoid damaging the components on the bottom of the PIC.

  4. For an FPC3 PIC, turn the ejector handle at the top of the PIC faceplate clockwise, then tighten the captive screw at the bottom of the faceplate to secure the PIC in the FPC.
  5. If the PIC 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.

  6. Insert the appropriate cables into the cable connectors on the PIC.
  7. 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

    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.

  8. Use one of the following methods to bring the 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:

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

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

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