ComNet Communication Networks of Danbury, Connecticut, has introduced a six-port, self-managed Ethernet switch, the CNGE2FE4SMS. The switch has four copper TX ports and two gigabit SFP Ethernet ports, allowing Ethernet data from the four TX ports to be combined and uplinked through the Gbps SFP port. Multiple units can be daisy-chained together through the gigabit backbone, supporting a large number of IP cameras, depending on the selected camera’s bit rate. The self-management feature requires no user intervention and is programmed to avoid flooding the network. It meets the IEEE 802.1x VLAN management standard.
