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.

Dual-Homing Configuration (applies only to “Turbo Ring V2”)
The “dual-homing” option uses a single Ethernet switch to connect two networks. The primary
path is the operating connection, and the backup path is a back-up connection that is activated in
the event that the primary path connection fails.
