Switch A: "Coupler"

To support the Ring Coupling function, select one EDS-726 (e.g., Switch A in the above figure) in the Turbo Ring and enter the Communication Redundancy page to enable “Ring Coupling.” Select one port as “coupling port” and then connect any port of the opposing EDS-726 (e.g., Switch C) in the adjacent Turbo Ring. Select another port as “coupling control port,” and connect this port to any port of the adjacent EDS-726 (e.g., Switch B) in the same Turbo Ring. The “Coupler” switch (Switch A above) will monitor switch B’s order from the “coupling control port” to decide if the coupling port’s backup path should be recovered.

ATTENTION

You only need to enable the “Ring Coupling” function on one EDS-726 (not on the opposing EDS-726 or an adjacent EDS-726). The Redundant Port, Coupling Port, and Coupling Control Port must all be assigned to different ports.

NOTE A particular EDS-726 does not need to be configured for both Ring Coupling and Ring Master.
