Installation Troubleshooting
During installation, first test the fiber and twisted pair 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 twisted pair and fiber connections before the link LEDs will
light!
To test a media converter by itself, first make sure you have an appropriate fiber
patch cable, then follow these steps to test:
Step 1
: Connect the media converter to the twisted pair device with a twisted
pair cable.
Step 2
: Loop a single strand of fiber from the transmit port to the receive port of
your media converter.
Step 3
: Verify that you have both twisted pair and fiber link (see LEDs, page 6)
on your media converter.
Make sure to use the appropriate twisted pair cable, and have the
crossover/pass-through switch set correctly, if your media converter does not
include AutoCross.
If using a high powered device (which is designed for long distance installations)
for a short distance installation, the fiber transmitters may overdrive the receivers
and cause data loss. If this is the case, you may need to add an optical
attenuator to your connection.
