Features: Small and light, three-dimensional surface grinding texture. Five Gigabit adaptive 10/100/1000 Mbs transmission ports, which can realize home or small office network links and easily achieve gigabit network speed. Plug and Play. It can work without any settings by connecting the network and power lines to the switch. Intelligent connection, automatic learning and update for MAC address, which can optimize the data path in the transmission process and ensure effective allocation to each port. LED dynamic indicator lamps can display the working state of the switch. LED lamp corresponds to user port, input interface and power interface one by one.
