Description
The ETX-201 managed Ethernet switch is equipped with four 10/100Mbps M12 ports with full power isolated IEEE 802.3af Power over Ethernet (PoE) and four 10/100/1000Mbps M12 ports.
The integrated UC-Ring technology makes it possible to use the switch in a ring topology to build a fault-tolerant network. The UC-Ring technology allows an unlimited number of switches in the ring while still ensuring a fast fault recovery time of less than 50ms. Moreover, switches with the UC-Ring technology and switches with a bypass relay may be combined. For even more complex redundant networks, a chaining of two rings is supported by the ETX-201.
An optional power supply redundancy provides additional up-time protection and increases the availability of the network.
