ComNet is introducing the CNFE4SMS, a four-port Self-Managed Ethernet Switch. The switch has four TX Ethernet ports that allow the Ethernet data from the three of the TX ports to be combined and inserted on to the network through the fourth TX port. The self-management feature requires no user intervention and is pre-programmed to avoid flooding the network. This port-configured Ethernet switch allows the user to create a virtual Local Area Network (VLAN) that manages the Ethernet data being transported, thereby preventing network flooding. Distances up to 100 meters are supported.
