The coupling between two networks is effected by the main line (thick blue
line). If the main line fails, the redundant line (thick blue dotted line) takes
over coupling the two networks.
The coupling is effected by two Switches.
The Switches send their control packets via a control line.
The device to which you connect the main line, and the device to which you
connect the redundant line, are partners as regards the coupling.
Connect the two partners via their ring ports.
If the STANDBY DIP switch is OFF, connect the main line to the coupling
port.
Select the Redundancy:Ring/Network Coupling dialog.
Select two-Switch main coupling
with control line
(see fig. 22) .
