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 above diagram.

The path connecting to the Head port is the main path, and the path connecting to the Tail port is the backup

path of the Turbo Chain. Under normal conditions, packets are transmitted through the Head Port to the LAN

network. If any Turbo Chain path is disconnected, the Tail Port will be activated so that packet transmission can

continue.
