Determining the Redundant Path for Turbo Ring V2
Master
For Turbo Ring V2, the backup segment is
the segment connected to the 2nd redundant
port on the master.
Please refer to Configuring Turbo Ring V2
later in this chapter.
Ring Coupling Configuration
For some systems, it may not be convenient to connect all devices in the system in a single
redundant ring, since some devices could be located in a remote area. For these systems, Ring
Coupling can be used to group devices into smaller redundant rings that communicate with each
other.
ATTENTION
In a VLAN environment, the user must set Redundant Port Coupling Port and Coupling
Control Port to join all VLANs, since these ports act as the backbone to transmit all packets of
different VLANs to the different TN series Ethernet switches.

Switch A and B in the above figure) in the ring, and another two TN series Ethernet switches in
the adjacent ring (e.g., Switch C and D).
