O-Chain
When connecting multiple O-Rings to meet your expansion demand, you can create an
O-Chain topology through the following steps.
1. Select two switches from the chain (Switch A & B) that you want to connect to the O-Ring
and connect them to the switches in the ring (Switch C & D).
2. In correspondence to the port connected to the ring, configure an edge port for both of the
connected switches in the chain by checking the box in the management page (see 4.1.2
Configurations).
3. Once the setting is completed, one of the connections will act as the main path, and the
ohter as the back up path.
