ComNet, Communication Networks, introduced a 6-port self-managed Ethernet switch, the CNGE2FE4SMS. The switch has four copper TX ports and two gigabit SFP Ethernet ports. This allows the Ethernet data from the four TX ports to be combined and uplinked through the Gbps SFP port, and allows multiple CNGE2FE4SMS units to be daisy-chained together through the gigabit backbone. The self-management feature requires no user intervention and is pre-programmed to avoid flooding the network.
