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.

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. With 5 plug-and-play ports, the switch is a perfect choice for the small workgroup to upgrade performance in a client/server environment. The ports can be connected to servers in full-duplex, or hubs in half-duplex. With low-cost connection per-port, the switch can also be set up for direct connection from the PCs. This relieves data bottleneck by giving each workstation a dedicated bandwidth on the network. For network starters, a convenient kit is available for ready installation. This kit includes a DES-1005D switch, 2 10/100Mbps Fast Ethernet PCI cards, and 2 6-meter (20-foot) UTP cables.
