Ring/Network Coupling
Activate the function in the "Operation" frame
Now connect the redundant line and the control line.
The displays in the "Select port" frame mean:
– "Port mode": The port is either active or in stand-by mode.
– "Port state": The port is either connected or not connected.
– "IP Address": The IP address of the partner, if the partner is already
operating in the network.
The displays in the "Information" frame mean:
– "Redundancy guaranteed": If the main line no longer functions, the
redundant line takes over the function of the main line.
– "Configuration failure": The function is incomplete or incorrectly
configured.
Figure 23: Two-Switch coupling with control line: Selecting the port and
enabling/disabling operation
To avoid continuous loops, the Switch sets the port state of the coupling
port to "off" if you:
– switch off the operation setting or
– change the configuration
while the connections are in operation at these ports.
