Effortless High Speed Networking Featuring easy access auto sensing 10/100 front Ethernet ports with two color LED indicators per port to quickly distinguish link, speed, and half/full duplex transmission status. The DES-108 switch also supports Auto MDI/MDIX Crossover allowing each port can be plugged directly to a server, hub, router, or switch using regular straight-through twisted-pair Ethernet cables. Support for IEEE 802.1p QoS is included, which organizes and prioritizes time-sensitive and important data for efficient delivery. Think Green The 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. Environmentally Friendly The DES-108 Gigabit switch was designed with the environment in mind. It is compliant with Energy Star Level V, CEC, and MEPS regulations which require the use of energy efficient power adapters. Built to comply with RoHS standards to minimize use of hazardous materials and is packaged with an EnergyStar Level V qualified power adapter all in a recyclable packaging making this product truly environmental friendly.
