The DES-1005A 5-Port 10/100 Mbps Fast Ethernet switch that allows you to quickly set up a wired network. These ports detect the network speed and auto-negotiate between 10BASE-T and 100BASE-TX、 as well as between full and half-duplex、 allowing you to get the maximum speed possible for each device connected to your network. All ports support automatic MDI/MDIX crossover. Each port can be plu.gged directly to a server、 hub、 router、 or switch using regular straight-through twisted-pair Ethernet cables.
