2.3 Redundant coupling of network segments
Coupling possibility
The redundant coupling of two network segments shown here as an example is only
possible between SCALANCE X-200IRT devices, since this requires the standby function of
the SCALANCE X-200IRT. This function can be configured with the WEB interface only.
The RM LED indicates whether the standby function is enabled.
The SCALANCE X-200IRT can be operated either as an RM or in standby mode.
