The ComNetTM CNFE4SMSPOE is a four-port self-managed Ethernet switch with uplink management functionality. It provides 4 ports operating at 10/100 Mbps and is designed to combine Ethernet data from the three electrical ports into a fourth electrical port and forward that data to the next network device. There is no programming required to use this product. The ComNet CNFE4SMSPOE comes pre-programmed, preventing network video flooding with a switch selection that allows the switch to be used as an uplink or as an unmanaged switch. All four ports can supply up to thirty (30) watts of power ("Power over Ethernet") and incorporate PoE+ features based on the IEEE 802.3at standard. It is "Plug-and-Play" easy to use. The ComNet CNFE4SMSPOE may be either wall mounted, rack mounted ("ComFit" packaging) or DIN-rail mounted with the use of the ComNet DINBKT1 adapter.
