Gigabit Ethernet Redundant Ring Capability (< 50 ms)

Ethernet has become the default data communications

medium for industrial automation applications. In fact,

Ethernet is often used to integrate video, voice, and

high-rate industrial application data transfers into one

network. Moxa switches come equipped with a redundant

Gigabit Ethernet protocol called Gigabit Turbo Ring. With

Gigabit Turbo Ring, if any segment of the network gets

disconnected, your automation system will be back to

normal in less than 300 ms (Turbo Ring) or 50 ms (Turbo

Ring V2).

NOTE

Port trunking and Turbo Ring can be enabled simultaneously to form a backbone. Doing so will increase the

bandwidth of the backbone, and also provide redundancy. For example, suppose that two physical ports, 1 and

2, are trunked to form trunk group Trk1, and then Trk1 is set as one Turbo Ring path. If port 1 gets

disconnected, the remaining trunked port, port 2, will share the traffic. If ports 1 and 2 are both disconnected,

the Turbo Ring will create a backup path within 300 ms.
