Ring Function
The two fibre ports of the device can be used to build up a ring structure.
Ring structures are commonly used in industrial and telecommunication environments
as they give redundant protection against failures at minimum cabling expense.
In normal operation the ring connection is logically interrupted by monitoring device
(switch configured for Ring Master mode). In case of failure (broken connection or
switch damage) the logically interrupted connection is activated by the Ring Master.
A big advantage of this solution is, that no additional central device is necessary for the
redundancy feature. Even if the ring master itself fails, the network will stay alive.
