Displays the status of the serial link between the active and idle controllers. See
LED 5 for further information.
• Blue pulsing Green = Link okay, data is being transferred.
• Green pulsing Blue = Link okay, no data is being transferred.
• Magenta pulsing Blue = Link error, no connection with the other controller.
Indicates; the other controller is not present/not running or the serial link is
not working.
• Orange Pulses = Error, received data for unconfigured device
Indicates; the other controller is configured differently from the controller
receiving the data or it has no configuration.

Serial Data Replication (Local Router Device)
The Serial Link is used to replicate LocalRouter device data between the active and
idle controllers. Replicated data includes; crosspoint status, module configuration
and port configuration.
• Off = Active Controller
• Flashing Green = Idle controller, receiving background update data.
• Flashing Orange = Idle controller, data synchronisation with Active
controller in progress.
Note: Do not fail-over to the idle controller until data synchronization is
complete and the LED is flashing green on the idle controller as there is a
risk that data will become corrupted and affect the operation of the router.
