Coupling Ring
Mark to enable Coupling Ring. Coupling Ring can be used to
divide a big ring into two smaller rings to avoid effecting all
switches when network topology change. It is a good application
for connecting two O-Rings.
Coupling Port
Link to Coupling Port of the switch in another ring. Coupling
Ring need four switch to build an active and a backup link.
Set a port as coupling port. The coupled four ports of four
switches will be run at active/backup mode.
Control Port
Link to Control Port of the switch of the same ring. Control Port
used to transmit control signals.
Dual Homing
Mark to enable Dual Homing. By selecting Dual Homing mode,
O-Ring will be connected to normal switches through two RSTP
links (ex: backbone Switch). The two links work as
active/backup mode, and connect each O-Ring to the normal
switches in RSTP mode.

Note:
We don’t suggest you to set one switch as a Ring Master and a Coupling Ring at the same time due to heavy
load.
5.1.3.3 O-Chain
O-Chain is the revolutionary network redundancy technology that provides the add-on
network redundancy topology for any backbone network, providing ease-of-use while
maximizing fault-recovery swiftness, flexibility, compatibility, and cost-effectiveness in
one set of network redundancy topology. O-Chain allows multiple redundant network
rings of different redundancy protocols to join and function together as a larger and more
robust compound network topology, i.e. the creation of multiple redundant networks
beyond the limitations of current redundant ring technology.
