Think Green! D-Link takes the lead in networking industry to release Green Ethernet technology with its new series of SOHO Gigabit switches. These environmentally-friendly devices decrease energy costs through the reduction of power consumption without sacrificing operational performance or functionality, providing benefits to both the ecosystem and Home/SOHO users. They are designed to help conserve energy, protect our environment from harmful substances, and reduce waste by using recyclable packaging. Automatically powers down ports that have no link Budgets power output for different Ethernet cable lengths Protecting the environment Complies with RoHS directive that restricts the use of certain hazardous materials Complies with WEEE (Waste Electrical and Electronic Equipment) directives that use recyclable packaging to help reduce waste that goes into theenvironment Inexpensive Gigabit solution for workgroup users from desktops Easily installable on desktop 16 or 24 10/100/1000Mbps Gigabit ports on Cat. 5 cable 32Gbps (16-port switch), 48Gbps (24-port switch) switching fabric capacity Auto MDI/MDIX cross over for all ports Secure store-and-forward switching scheme Full/half-duplex for Ethernet/Fast Ethernet speeds Blazing 2000Mbps full duplex for Gigabit speed IEEE 802.3x Flow Control Plug-and-Play installation Please note: networking components such as switches, routers and wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
