The Viper range of M12 ultra-slim rugged Ethernet switches have a MTBF (Mean Time Between Failure) of more than a 100 years, making them ideal for severe duty and safety-critical applications. The range includes two eight-port managed Ethernet switches with or without ring functionality.With a reconfiguration time of less than 20 milliseconds, Westermo´s novel FRNT (Fast Recovery of Network Topology) technology is the fastest protocol on the market to re-configure a large network in the event of any link or hardware failure.
