5.5 Redundant Coupling
The control intelligence built into the switch allows the redundant coupling of
HIPER-Rings and network segments. Two network segments can be
connected via two separate paths with one of the following switches:
D RS2-16M
D RS20/RS30/RS40
D RSR20/RSR30
D MICE (Rel. 3.0 or higher)
D MS20/MS30
D PowerMICE
D MACH 1000
D MACH 3000 (Rel. 3.3 or higher)
D MACH 4000
The switch in the redundant line and the switch in the main line inform each
other about their operating states by using control frames via the ethernet or
via the control line.
Note: For redundancy security reasons, the Rapid Spanning Tree protocol
and redundant network/ring coupling may not be enabled simultaneously.
Note: The network that connects the master and the slave must always be a
HiPER-Ring. The coupling switch in single mode also must have a HiPER-
Ring Configured.
Further information concerning this function you will find in the User Manual
”Redundancy Configuration”.
These commands allow you to configure the redundant coupling of network
segments.
