Redundant linking of rings
Apart from media redundancy in ring topologies, as of firmware version 1.2, the IE switches
also support the redundant linking of HRP rings (including interrupted HRP rings = linear
topology). In the redundant link, two HRP rings are connected together via two Ethernet
connections. This is achieved by configuring a master/slave device pair in one ring so that
the devices monitor each other over the ring ports and, in the event of a fault, redirect the
data traffic from one Ethernet connection (standby port of the master) to another Ethernet
connection (standby port of the slave).
For more detailed information on Ethernet cabling and the topological location of master and
slave, refer to the "Operating Instructions SCALANCE X-400 Industrial Ethernet Switches".
Note
To use the redundant ring linking function, HRP must be enabled.

Standby Connection Name
Here, enter the name for the standby connection. The master/slave device pair is defined by
this name (both must be in the same ring). This is achieved by entering the same name on
