D-Link GO-SW-5G/8G 5/8-port Gigabit Easy Desktop Switch • Power Saving Technology: • Power saving by link status. If there is no link on a port, such as when there is no computer connected to the port or the connected computer is powered off, D-Link's Green Technology will enter a "sleep mode", drastically reducing power used for that port. • Power saving by cable length: 0~20m, 21~50m, 51~100m. D-Link's Green Technology detects the length of connected Ethernet cable and adjusts power usage accordingly without affecting performance. This way, a port connected to a less than 20m cable only uses as much power as it needs, instead of using full power, which is only needed for 100m cables. Switching Technology Another key development pushing the limits of Ethernet technology is in the field of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by making it possible for a local area network to be divided into different segments that do not compete with each other for network transmission capacity, decreasing the load on each segment. The switch acts as a high-speed selective bridge between the individual segments. Traffic that needs to go from one segment to another (from one port to another) is automatically forwarded by the switch, without interfering with any other segments (ports). This allows the total network capacity to be multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet or Gigabit Ethernet networks, a Switch is an effective way of eliminating problems of chaining hubs beyond the "two-repeater limit." A Switch can be used to split parts of the network into different collision domains, for example, making it possible to expand your Fast Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between existing 10Mbps networks and new 100Mbps networks. Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router and the setup and maintenance required make routers relatively impractical. Today's Switches are an ideal solution to most kinds of local area network congestion problems. Switch Description The GO-SW-5G/GO-SW-8G Switch is equipped with five ports providing dedicated 10, 100, or 1000 Mbps bandwidth. These ports can be used for connecting PCs, printers, servers, routers, Switches, hubs, and other network devices. The five multi-speed ports use standard twisted pair cabling and are ideal for segmenting networks into small, connected subnets. Each port can support up to 2000 Mbps of throughput in full-duplex mode. This stand-alone Switch enables the network to use some of the most demanding multimedia and imaging applications concurrently with other user applications without creating bottlenecks. Features The GO-SW-5G/GO-SW-8G 5/8-port Gigabit Easy Desktop Switch was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. • 5/8 10/100/1000BASE-T Gigabit Ethernet ports • D-Link's Green Technology · IEEE 802.3az Energy-Efficient Ethernet (EEE) · Power Saving Technology: · Power saving by link status. · Power saving by cable length • Supports Auto-Negotiation for 10/100/1000Mbps and duplex mode • Supports Auto-MDI/MDIX for each port • Supports Full/Half duplex transfer mode for 10 and 100Mbps • Supports Full-duplex transfer mode for 1000Mbps • Full wire speed reception and transmission 2
