Redundant Coupling Of Network Segments - Siemens SCALANCE X-200 Configuration Manual

1.7

Redundant coupling of network segments

Coupling option
The coupling of two network segments shown here as an example is possible with X-
200IRT, X-300 and X-400 IE switches. This requires the standby function of these devices
that can be set via Web Based Management or CLI.
If the standby function is enabled, this is signaled on X-200IRT IE switches by the RM LED.
A SCALANCE X-200IRT can be operated either as redundancy manager or in standby
mode.
The following figure shows the redundant link of SCALANCE X-200 rings with two
SCALANCE X-200IRT devices:
Figure 1-10
For a redundant link as shown in the figure, two X-200IRT IE switches 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-200 Industrial Ethernet Switches".
