Troubleshooting

General Troubleshooting
• During installation, first test the fiber and BNC connections with all
troubleshooting features disabled; then enable these features, if desired, just
before final installation. This will reduce the features' interference with testing.
• When working with units where the features cannot be disabled, you must
establish BOTH your BNC and fiber connections; the NO LNK LEDs should not
be lit (i.e. NO LNK LED not lit = good connection, NO LNK LED lit = problem).
• To test a media converter by itself, first make sure you have an appropriate fiber
patch cable, then follow these steps to test:
1. Connect the media converter to the BNC device with a coax cable.
2. Loop a single strand of fiber from the transmit port to the receive port of your
media converter.
3. Verify that you have a valid connection for both the BNC and fiber ports on
your media converter.
• If there is trouble with link connectivity, make sure the connection is made using
75W Coax cable.
