Everything is hooked up but nothing is working. What should I do?

When you troubleshoot issues with a fiber media converter, there are some quick tests that you can complete to rule out potential problems. To identify what the source of the issue is, observe the power LED, LAN LEDs, and fiber link LED on the units.

If the power LED is not illuminated for the transmitter or the receiver, complete the following:

  • Make sure that you are using the provided power adapter(s).

  • Make sure that the adapter is plugged into a compatible wall outlet.

  • Make sure that the adapter is plugged into both the transmitter and receiver.

If another LED is not operating as expected, make sure that the components in your setup are working correctly. To test your setup components, try the following:

  • Use the cables, fiber media converter, and network devices (including SFPs, if applicable) in another setup to see if the problem is with the components or the setup.

  • Use different cables, fiber media converter, and network devices (including SFPs, if applicable) in your setup to see if the problem persists. Ideally, you should test components that you know work in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

Make sure that the DIP switches are set to the following:

  • DIP switches should be identical on both local and remote units. By default, DIP switches are set to Off (the switch is pointing up).

  • For more information about the advanced configuration options, refer to the manual for your product.

If you cannot establish a network connection between your local and remote units, you need to do the following to make sure that the issue is not related to the network configuration:

  • Use two computer systems directly connected to the fiber media converter LAN ports.

  • Open a command prompt on Computer 1 and ping Computer 2.

If the issue is not related to the network configuration, you should receive a response from Computer 2.
