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.
