DES-1008A The DES-1008A 8-Port 10/100 Switch is is an 8-port 10/100 Mbps Fast Ethernet switch that allows you to quickly set up a wired network. Connect the DES-1008A to multiple computers together to share files and folders， or connect it to a router to share an Internet connection. Auto-sensing 10/100 Ports The D-Link DES-1008A 8-Port 10/100 Switch uses auto-sensing 10/100 Mbps ports， allowing a small workgroup to flexibly connect to Ethernet and Fast Ethernet devices to create an integrated network. These ports detect the network speed and auto-negotiate between 10BASE-T and 100BASE-TX， as well as between full and half-duplex， allowing you to get the maximum speed possible for each device connected to your network. Auto MDI/MDIX CrossOver All ports support automatic MDI/MDIX crossover， eliminating the need for crossover cables or uplink ports. Each port can be plugged directly to a server， hub， router， or switch using regular straight-through twisted-pair Ethernet cables. Flow Control for Secure Transmission 802.3x flow control on each port minimizes dropped packets when the port’s receiving buffer is full. This gives you a more reliable connection for all of your connected devices， ensuring smooth and uninterrupted network connection.Key Features Built-in D-Link Green Technology Inexpensive Gigabit solution for Home/Media Center 8 10/100/1000 Mbps  ports 10/16 Gbps switching fabric Auto MDI/MDIX crossover for all ports Secure store-and-forward switching scheme Full/half-duplex for Ethernet/Fast Ethernet speeds IEEE 802.3x Flow Control Supports 9，216 Byte Jumbo Frames Supports IEEE 802.1p QoS (4 Queues， Strict Mode) Supports Cable Diagnostics Function RoHS compliant Plug-and-play installation Standards IEEE 802.3 10BASE-T Ethernet (twisted-pair copper) IEEE 802.3u 100BASE-TX Fast Ethernet (twisted-pair copper) IEEE 802.3ab 1000BASE-T Gigabit Ethernet (twisted-pair copper) ANSI/IEEE 802.3 Nway autonegotiation IEEE 802.3x Flow control IEEE 802.1p QoS IEEE 802.3az Energy-Efficient Ethernet (EEE) Protocol CSMA/CD Data Transfer Rates Ethernet: 10 Mbps (half duplex) 20 Mbps (full duplex) Fast Ethernet: 100 Mbps (half duplex) 200 Mbps (full duplex) Ethernet: 2000 Mbps (full duplex) Topology Star Media Interface Exchange Auto MDI/MDIX adjustment for all ports Network Cables 10BASE-T: UTP CAT 3/4/5/5e (100 m max.)
