NUAGE Firmware Update Guide 12
About Failsafe Mode
During normal operation, software must be loaded from a flash memory drive during operations to use the Dante
module integrated in the Nuage I/O. However, data in a flash memory drive may occasionally become corrupted, as
with any other storage device.
In many cases, such data corruption is caused by turning the Nuage I/O power off during firmware upgrading.
The Dante module has a specially protected flash drive section in order to recover from such a condition. When the
main section is damaged, the program stored in the protected area is activated and the Dante module goes into
“failsafe mode.
To restore the Dante module in failsafe mode, a recovery image needs to be sent from the Firmware Update
Manager.
To check if the Dante module is in failsafe mode, use Dante Controller: the respective device is displayed in red in
the network grid view of the Dante Controller (version 3.1.x or higher).
Further, a message “NETWORK AUDIO MODULE FAILED AND WAS RESTARTED. appears also in the Nuage I/O
screen, so you may check that the DANTE version information is not displayed in the version field of the Nuage I/O
unit.
Described below are the procedures to recover the Dante module integrated in the Nuage I/O unit.
1. Turn off the power to the computer and the Nuage I/O.
2. Separate the Nuage I/O from the Dante network.
3. Connect the Dante [PRIMARY] connector on the rear panel of the Nuage I/O unit to the Ethernet connector on the
computer using an Ethernet cable.
4. Turn the computer power on and login with administrative privileges.
5. Turn on the power to the Nuage I/O.
