Troubleshooting
If trouble is encountered, verify all copper and fiber connections and settings. If any of the DIP switches
were changed, you must recycle the power by flipping switch 6 to RST (Reset) and ON again to enable
the settings. Refer to the LED Indicators on the front panel, they show availability of power, modes of
operation, and data being received by the fiber and TP port.
