Redundant Linking Of Network Segments - Siemens SCALANCE X-400 Operating Instructions Manual

1.2.4

Redundant Linking of Network Segments

The example of redundant linking of two network segments as shown here is pos-
sible only when linking between X414 because the standby function of the X414 is
required.

Figure 1-6
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 devices must be configured within
a network segment. This configuration is set in Web Based Management, Com-
mand Line Interface or using SNMP access. For more detailed information, refer to
the Configuration Manual SCALANCE X-400 Industrial Ethernet Switches.
