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

igabit Ethernet protocol called Gigabit Turbo Ring. With

Gigabit Turbo Ring, if any segm

ent 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 s

hare the traffic. If ports

1 and 2 are both disconnected,

the

Turbo Ring will create a backup path within 300 ms.
