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 enabled

Here, you decide whether or not the standby function is 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
