4.2 Ring topology
The ring topology meets the requirements of the standard EN 54-16.
The ring topology is the standard topology.
The ring topology has the same function as the chain topology. The difference to
the chain topology is that the final Ethernet switch is connected to the first to form a
ring.
The ring topology can accommodate a maximum of 32 hubs.
Single redundant ring topology

NOTICE
'Ethernet switch (1x4)' PN1001-A1 can't be used for the ring topology
Use 'Planet IGS-10020MT Ethernet Switch' PN2005-A1 instead
Double redundant ring topology
The double redundant ring topology can increase protection against failure and
exceeds the requirements of the standard EN 54-16.
Each audio matrix and each network participant are connected redundantly via the
Ethernet ports to two Ethernet switches A and B.
