Redundant coupling of network segments

Redundant coupling of network segments
The example of redundant coupling of two network segments as shown here, for example rings
with a redundancy manager, can be implemented homogeneously with all SCALANCE X300
variants.

In this case, network segments are rings with a redundancy manager (RM). The rings can also
be interrupted at one point (linear topology).
For a redundant link as shown in the figure, two IE Switches X-300 must be configured within
a network segment. This configuration is set in Web Based Management, Command Line
Interface or using SNMP access. For more detailed information, refer to the "Configuration
Manual SCALANCE X‑300 and SCALANCE X-400 Industrial Ethernet Switches". The two
