The Turbo Chain Concept
Moxa’s Turbo Chain is an advanced software-technology that gives network administrators the flexibility of
constructing any type of redundant network topology. When using the “chain” concept, you first connect the
Ethernet switches in a chain and then simply link the two ends of the chain to an Ethernet network, as
illustrated in the following figure.
Turbo Chain can be used on industrial networks that have a complex topology. If the industrial network uses a
multi-ring architecture, Turbo Chain can be used to create flexible and scalable topologies with a fast
media-recovery time.
Setting Up Turbo Chain
1. Select the Head switch, Tail switch, and Member switches.
2. Configure one port as the Head port and one port as the Member port in the Head switch, configure one
port as the Tail port and one port as the Member port in the Tail switch, and configure two ports as
Member ports in each of the Member switches.
3. Connect the Head switch, Tail switch, and Member switches as shown in the diagram.
