Replacing a CFP Transceiver

C form-factor pluggable (CFP) transceivers are hot-insertable and hot-removable. Removing a transceiver does not interrupt line card functioning, but the removed transceiver no longer receives or transmits data.

You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

Removing a CFP Transceiver

To remove a CFP transceiver:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the CFP transceiver. Have ready a rubber safety cap for the CFP transceiver and the cable.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  3. Label the cable connected to the CFP transceiver so that you can later reconnect it to the correct CFP transceiver.
  4. Disconnect the cable from the CFP transceiver. Immediately cover the transceiver and the end of the 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 cable connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

  5. Arrange the cable in the cable management system 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.
    CAUTION:

    Avoid bending 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.

  6. Unscrew the screws from the CFP transceiver faceplate to unseat the CFP transceiver from the line card. Pull the CFP transceiver out of the line card and place it on the antistatic mat or in the electrostatic bag.

Installing a CFP Transceiver

To install a replacement CFP transceiver:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Verify that a rubber safety cap covers the CFP transceiver, installing one if necessary.
  3. Orient the CFP over the port in the line card so that the connector end will enter the slot first and the CFP connector faces the appropriate direction.
  4. Slide the CFP into the slot. If there is resistance, remove the CFP and flip it so that the connector faces the other direction.
  5. Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.
    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 cable connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

  6. Arrange the cable in the cable management system 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.
    CAUTION:

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

    CAUTION:

    Avoid bending 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.

  7. Verify that any status LEDs on the line card faceplate indicate that the CFP is functioning correctly. For more information about the line card LEDs, see the MX Series 5G Universal Routing Platform Interface Module Reference. You can also verify line card functioning by issuing the show chassis fpc pic-status command.
