About Failsafe Mode - Yamaha HY144-D-SRC Firmware Update Manual

The Dante module integrated in the HY144-D-
SRC 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 Dante
Firmware Update Manager.
If the red ERROR indicator of the HY144-D-SRC 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.

About 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).
