About Failsafe Mode
The Dante module integrated in the HY144-D may become unusable due to data corruption if the
Dante device is powered-off during a firmware update.
To recover from such a state, the Dante module will enter "failsafe mode."
To restore the Dante module from failsafe mode, a recovery image must be sent from the Firmware
Update Manager.
If the red ERROR indicator of the HY144-D is lit, it may be that the Dante module is in failsafe mode.
Use Dante Controller to check whether the Dante module is in failsafe mode.
A Dante module that is in failsafe mode is shown as a red device name in the network grid view of
Dante Controller (version 3.1.x or later).
