The ComNet™ CNFE4+1SMS(M,S)2 is a five-port self-managed Ethernet switch with uplink management functionality. It provides 4 ports operating at 10/100Mbs and is designed to combine Ethernet data from the four electrical ports into a single optical port and forward that data to the next network device, using two-fiber ST or SC optical connectors. There is no programming required to use this switch. The ComNet CNFE4+1SMS comes pre-programmed, preventing network video flooding with a switch selection that allows the fiber port to be used as an uplink or as an unmanaged switch. It is “Plug-and-Play” easy to use. LED indicators confirm the operating status of this device. The ComNet CNFE4+1SMS may be either wall mounted, rack mounted (“ComFit” packaging) or DIN –rail mounted with the use of the ComNet DINBKT1 adapter.
