The D-Link DES-108 8-Port 10/100 Fast Ethernet Switch provides eight Fast Ethernet auto-sensing ports for connecting multiple computer devices to your network. Once you've connected the switch to your network via one Fast Ethernet port, you will have seven other ports for connecting printers, scanners, storage, backup devices and more. Support for Quality of Service (QoS) means the switch will prioritize network traffic that is sensitive to lags, such as video streaming or VoIP calls. The switch is unmanaged and plug-and-play, so you need not install software first to use it or configure settings for it later. Plus, the diagnostic LEDs on the front panel let you know if there are any connection issues, helping you troubleshoot problems as they arise.
