Redundant Coupling Of Network Segments - Siemens SCALANCE X-200 Operating Instructions Manual

2.7

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 the WEB interface or CLI.
If the standby function is enabled, this is signaled on X-200 IE switches by the RM-LED.
The SCALANCE X-200IRT can be operated either as an RM or in standby mode.
