MASTER
or
SLAVE
).
Both controllers need to be connected to the DHD network and the Controller network. If you need to add additional
switches, please note the DHD Network Specifications.
Update the firmware of the controller modules one after each other. Therefore, unplug the slave controller module and
update the firmware of the master. Afterwards, unplug the master module and plug in the slave controller to update the
slave module. Moreover, the installed firmware version must support the controller redundancy option (firmware version
06.05.12 or higher). The same applies to the kernel version (kernel version 01.00.19 or higher).
Important
Do never use the firmware versions 06.05.12 or higher together with older
firmware versions in the communication controllers of the same frame
simultaneously.
You have to transfer the Toolbox5 configuration to the master controller. The module or the slot itself is not important,
only that the module is currently running as master. The slave automatically gets a copy from the master. It is not useful
to transfer a configuration to the slave controller, since it is overwritten by the version saved in the master. Please note
that this copying process may take some minutes.
How to upgrade the firmware if the communication controller redundancy is already in
use?
With the above mentioned procedure you loose the connection to the device, because in this process both communication
controller modules need to be unplugged. If the communication controller redundancy is already working, you can use
another way to avoid this interruption. Proceed as follows if the currently installed firmware version on the communication
controller modules is 06.05.12 or higher:
·
Update the firmware of the SLAVE controller and execute a firmware reset. This step does not influence the audio signal
flow, because the SLAVE controller is not in use at this time.
·
Afterwards, update the firmware of the MASTER controller and execute a firmware reset. The SLAVE controller takes
over and becomes MASTER. Vice versa the previous MASTER changes to SLAVE mode. This step will interrupt the audio
for approx. 1 or 2 seconds.
