The D-Link DES-1005D is a 5-port unmanaged Ethernet switch delivering 10/100 Mbps connectivity for SOHO network expansion. This fanless desktop unit supports both 10BASE-T and 100BASE-TX standards with automatic MDI/MDI-X negotiation on each port. The switch operates via store-and-forward transmission, maintains a 1K MAC address table per device, and delivers 1 Gbps aggregate switching capacity with packet forwarding rates of 14,880 pps per port at 10BASE-T and 148,800 pps per port at 100BASE-TX (half-duplex).
