The D-Link DES-108 is a plug-and-play networking switch that offers D-Link?s Green Technology to save energy and reduce heat, which in turn extends product life without sacrificing performance or functionality. The switch supports IEEE 802.3az Energy-Efficient Ethernet (EEE) which detects when a connected computer is shut down or when there is no Ethernet traffic, at which time the switch will automatically power down the idle port, saving a substantial amount of power. The DES-108 provides eight ports for easy expansion of your network for connecting printers, scanners, storage, and backup devices to any network.
