The coupler switch (i.e., Switch A) will monitor switch B through the coupling control port to determine whether
or not the coupling port’s backup path should be recovered.

Backup Path
Note that the ring coupling settings for a “Turbo Ring V2” ring are different from a “Turbo Ring” ring. For
Turbo Ring V2, Ring Coupling is enabled by configuring the “Coupling Port (Primary)” on Switch B, and the
“Coupling Port (Backup)” on Switch A only. You do not need to set up a coupling control port, so that a
“Turbo Ring V2” ring does not use a coupling control line.
The “Coupling Port (Backup)” on Switch A is used for the backup path, and connects directly to an extra
network port on Switch C. The “Coupling Port (Primary)” on Switch B monitors the status of the main path,
and connects directly to an extra network port on Switch D. With ring coupling established, Switch A can
activate the backup path as soon as it detects a problem with the main path.
ATTENTION
Ring Coupling only needs to be enabled on one of the switches serving as the Ring Coupler. The Coupler must
designate different ports as the two Turbo Ring ports and the coupling port.
NOTE You do not need to use the same EDS unit for both Ring Coupling and Ring Master.
Dual-Ring Configuration (applies only to “Turbo Ring V2”)
The “dual-ring” option provides another ring coupling configuration, in which two adjacent rings share one
switch. This type of configuration is ideal for applications that have inherent cabling difficulties.
