Removing a T1600 XFP

10-Gigabit small form-factor pluggables (XFPs) are hot-insertable and hot-removable. Removing an XFP does not interrupt PIC functioning, but the removed XFP no longer receives or transmits data.

To remove an XFP:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the XFP. Have ready a rubber safety cap for the XFP transceiver and the cable.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Label the cable connected to the XFP so that you can later reconnect it to the correct XFP.
  4. Disconnect the cable from the XFP. Immediately cover the transceiver and the end of the cable with a rubber safety cap.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. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.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. Pull the ejector handle away from the XFP faceplate to unseat the XFP from the PIC. Pull the XFP out of the PIC and place it on the antistatic mat or in the electrostatic bag.

Installing a T1600 XFP

To install a replacement XFP:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Verify that a rubber safety cap covers the XFP transceiver, installing one if necessary.
  3. Orient the XFP over the port in the PIC so that the connector end will enter the slot first and the XFP connector faces the appropriate direction.
  4. Slide the XFP into the slot. If there is resistance, remove the XFP 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.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. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.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 the status LEDs on the PIC faceplate indicate that the XFP is functioning correctly (there is an LED for each XFP port). For more information about the PIC LEDs, see the T1600 Core Router Interface Module Reference. You can also verify PIC functioning by issuing the show chassis fpc pic-status command described in Maintaining T1600 PICs and PIC Cables.
