Is there a official setup guide for redundancy using
Nope, it’s plug and play. no need to set up anything and actually don’t recommend adjusting settings.
Just have a redundant physical connection between the two identical switches. If one cable is cut or disconnected, the connection is kept via the second cable.
Please note : LAG feature is now supported with RJ45 ports to be used for a redundant connection between network switches. When using this feature, please use only supported ethernet cables with identical specifications.
Having them up running but having a big “lag” in sound when disconnecting one of the redundant cables
Is the switch with default settings or are they pre-programmed?
Have a ticket with support also to spread some light on this issue.
I would not be able to help with this, let’s see what support say.
