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
illuminate.
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.
