Installing the SFP Transceiver in the LN2600 Router


You can install up to eight SFP transceivers in the LN2600 router. The SFP transceivers are hot-removable and hot-insertable. You can remove and replace them without powering off the LN2600 router or disrupting the router functions.


Do not look directly into transceivers or into the ends of fiber-optic cables connected to a transceiver. Fiber-optic transceivers emit laser light that can damage your eyes.


When handling fiber-optic transceivers and fiber-optic cable, observe the following precautions:

  • 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.

  • Do not bend 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.

  • 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.

To install an SFP transceiver:

  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 SFP transceiver, installing one if necessary.
  3. Orient the SFP over the port in the router so that the connector end will enter the slot first and the SFP connector faces the appropriate direction.

  4. Slide the SFP into the slot.
  5. Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.
  6. Verify that the SFP is installed by entering the CLI show chassis hardware detail command.
