Activate the function in the “Operation” frame (see fig. 53).
You now connect the redundant line.
The displays in the “Select port” frame mean (see fig. 53):
– “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 (see fig. 59):
– “Redundancy guaranteed”: One of the lines affected can fail, as a
redundant line will then take over the function of the failed line.
– “Configuration failure”: The function is incomplete or incorrectly
configured.
