If there are 2N EDS-726 units (an even number)
in the Turbo Ring, then the backup segment is
one of the two segments connected to the
(N+1)st EDS-726 (i.e., the EDS-726 unit directly
opposite the Master).
When the number of EDS-726 units in the Turbo Ring is odd.

Segment N+1
If there are 2N+1 EDS-726 units (an odd
number) in the Turbo Ring, with EDS-726 units
and segments labeled counterclockwise, then
segment N+1 will serve as the backup path.
For the example shown here, N=1, and therefore
N+1=2.
For some systems, it may not be convenient to connect all devices in the system to make one BIG
redundant ring, since some devices could be located in a remote area. The “Ring Coupling”
function of Turbo Ring can help you separate those distributed devices into different smaller
redundant rings, but in such a way that they can still communicate with each other. The figure
below illustrates how to couple two Turbo Rings.
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-726 units.
