. The DES-1008D is an unmanaged 10/100 Mbps switch designed to enhance small workgroup performance while providing a high level of flexibility. The switch comes with 8 10/100 Mbps ports allowing a small workgroup to flexibly connect to Ethernet & Fast Ethernet & integrate. These intelligent ports detect the network speed & auto-negotiate between 100BASE-TX & 10BASE-T as well as between full- & 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. All ports support auto-negotiation of MDI/MDIX cross over. This eliminates the need for cross over cables or uplink ports. Any port can simply plug to a server a hub or a switch using the usual straight-through twisted-pair cable..
