The DES-1005D is an unmanaged 10/100Mbps switch designed to enhance small workgroup performance while providing a high level of flexibility. Powerful yet easy to use this device allows users to simply plug any port to either a 10Mbps or 100Mbps network to multiply bandwidths boost response time and satisfy heavy load demands. The switch comes with 5 10/100Mbps ports allowing a small workgroup to flexibly connect to Ethernet ad Fast Ethernet and integrate. These intelligent ports detect the network speed and auto-negotiate between 100BASE-TX and 10BASE-T as well as between full- and half-duplex. All ports support 802.3x flow control. This function minimizes dropped packets by sending out collision signals when the port\'s receiving buffer is full. Flow control is available in the full-duplex mode.
