The D-Link DGS-1005G 5-port Gigabit Switch was designed with the environment in mind. It is compliant with energy Star level V, as well as with the strict CEC and MEPS regulations that require the use of energy efficient power adapters. The DGS-1005G switch is also built to follow RoHS standards to minimize use of hazardous materials, and uses recyclable packaging that helps reduce waste, complying with the WEEE directive. The DGS-1005G switch helps you conserve energy automatically through several methods. It automatically powers down ports that have no link activity, allowing the switch to save energy by cutting power usage for unused ports or ports connected to computers that have been shut down. It can also detect connected cable lengths and adjusts power usage accordingly, helping you save energy without effecting networking performance.
