Communication Redundancy Turbo Ring
2-3
When the Number of Switches in the Turbo Ring is Odd
If there are 2N+1 switches (an odd number) in the “Turbo Ring”
ring, with switches and segments labeled counterclockwise,
then segment N+1 will serve as the backup path.
For the example shown here, N=1, so that N+1=2.
Determining the Redundant Path of a “Turbo Ring V2” Ring
For a “Turbo Ring V2” ring, the backup segment is
the segment
connected to the 2nd redundant port on the master.
See Configuring “Turbo Ring V2” in the
Configuring “Turbo Ring”
and “Turbo Ring V2” section below.
Ring Coupling Configuration
For some systems, it may not be convenient to connect all devices in the system to create one BIG redundant
ring, since some devices could be located in a remote area. For these systems, Ring Coupling can be used to
separate the devices into different smaller redundant rings, but in such a way that they can still 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 different
switches.
