“Turbo Ring” rings with an odd number of EDS-728 units.
If there are 2N+1 EDS-728 units (an odd
number) in the “Turbo Ring” ring, with EDS-728
units 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, you must set “Redundant Port,” “Coupling Port,” and “Coupling
Control Port” as “Trunk Port,” since these ports act as the “backbone” to transmit all packets of
different VLANs to different EDS-728 units.
