Viprion 2400 redundancy cabling

Does this means i can't use the failover ethernet port for anything and should use SFP port for network failover?

hardware serial failover is not supported in viprion platform. you have to use network failover.

when configuring network failover, it is the best practice to use both tmm and mgmt ports.
