MB300E Network redundancy
We have two separate or redundant MB300E networks 11 & 12 using two ethernet switches and it is connected as an independent two networks up to our multiplexer.
It follwows your MasterNet user manual connectivity on page 129 Fig 4-13.
Some one would like to connect the two switchs by a cable and to connect on switch to the only available ethernet port in our radio.
What do you think
MB300 redundancy stipulates two physically separated networks. A disturbance on one of the networks will most likely not affect both.
By connecting the two networks the isolation is lost and the two will in practice become one common with increased bandwidth dissipation since multicast traffic will propagate on both networks.
The proposition does not sound like a good idea to me.
I have to agree with Stefan.....
Will it work ? Yes - probably. Note that MB300E is not a complete TCP/IP. There are differences in the ethernet packet used by Masterbus that in my experience can cause it to be rejected by some switches.
Will it compromise your redundancy ? - Yes absolutely. The most fragile part of your network ( the radio signal) is not redundant.
Its a pretty bad idea because (without empirical data) the probability of failure appears high. Whether it is "safe" depends on your requirements for reliability and the consequences of failure.
