Moxa’s breakthrough Turbo Chain redundancy technology dramatically simplifies the creation of multiple redundant connections over a widely dispersed power distribution network. With Turbo Chain, PowerTrans Ethernet switches can be daisy-chained together from one Ring Main Unit (RMU) to another, with each “chain” connected to the distribution substations. If a chain segment fails, the blocked path will rapidly activate within 20 milliseconds to ensure high network availability. Moxa’s breakthrough Turbo Chain flexible redundancy technology frees system builders from the costly limitations of conventional ring architecture. Compared with conventional ring topology, Turbo Chain eliminates the need for kilometers of extra cable and additional Ethernet ports to form ring coupling paths. In addition, the PowerTrans PT-7828 Layer 3 Ethernet switches also support Open Shortest Path First (OSPF), which uses “link state” instead of “hop count” to determine the network route. Compared to Routing Information Protocol (RIP), OSPF has faster network convergence and consumes less network traffic.
