Master
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

way that they can still communicate with each other.
ATTENTION
In a VLAN environment, the user must set “Redundant Port,” “Coupling Port,” and “Coupling
Control Port” to join all VLANs, since these ports act as the “backbone” to transmit all packets
of different VLANs to different EDS units.

To configure the Ring Coupling function for a “Turbo Ring” ring, select two EDS units (e.g.,
Switch A and B in the above figure) in the ring, and another two EDS units in the adjacent ring
(e.g., Switch C and D).
Decide which two ports in each switch are appropriate to be used as coupling ports, and then link
them together. Next, assign one switch (e.g., Switch A) to be the “coupler,” and connect the
