The D-Link DES-1005D is a powerful desktop Dual Speed 5-port 10/100Mb Ethernet/Fast Ethernet NWay auto-negotiating Switch. It functionally eliminates unnecessary traffic and relieves data congestion by delivering dedicated bandwidth for each of the five ports. An individual port can connect to either an Ethernet or Fast Ethernet device. NWay auto-negotiation automatically determines the transmission speed of the attached device on each port.The DES-1005D provides dynamic buffer allocation that employs network-load balancing for faster data handling. The uplink interface connection enables easy expansion. The DES-1005D uses fast store and forward architecture to ensure low latency and high data integrity. It supports stacking though the MDI II uplink RJ-45 connection that is shared with port 1 for flexible media connection and expansion capabilities.
