Troubleshooting the Backbone:
You can see the status of an individual Zone as it is connected to the Bridge by observing the LED for that Bridge Port, and interpreting its Blink Pattern when in port status mode.
Port Status Blink Pattern Meaning
1 Blink Zone is healthy.
2 Blinks Upstream Bridge or Gateway is detected.
4 Blinks Downstream Bridge is detected.
5 Blinks Too many Adds/Deletes on the port.
Reset the Bridge.
6 Blinks Two Bridge ports are cabled together, creating a Bridge Loop. Check Bridge wiring and remove the loop.
