3.3 Example of Fast HIPER-Ring
This example can be set up with models RSR20, RSR30 and MACH 1000.
A network contains a backbone in a line structure with 3 devices. To increase
the redundancy reliability of the backbone, you have decided to convert the
line structure to a ring redundancy. In contrast to the previous example, you
require a very short switching time in a redundancy case (about 10 ms).
Only RSR20/RSR30 and MACH 1000 devices are being used, so you decide
on the Fast HIPER-Ring as the ring redundancy protocol. You use ports 1
and 2 in module 1 of the devices to connect the lines.

The following example configuration describes the configuration of the ring
manager device (1). The two other devices (2 to 3) are configured in the
same way, but without activating the ring manager function. A VLAN is not
used for this example.
