The D-Link 5-Port Gigabit Unmanaged Desktop Switch creates a blazing fast network for your office, as its Gigabit Ethernet ports provide high-speed wired connections for up to five PCs or other devices. The DGS-1005A also features QoS, which prioritizes network traffic so that time-sensitive data is delivered efficiently, even during bursts of high data traffic. The 5-Port Gigabit Unmanaged Desktop Switch helps you conserve energy automatically through several methods. It automatically powers down ports that have no link, allowing the switch to save a substantial amount of power by cutting power usage for unused ports or ports connected to computers that have been shut down. The 5-Port Gigabit Unmanaged Desktop Switch was designed with the environment in mind, and is compliant with Energy Star Level V, as well as with the stringent CEC and MEPS regulations that require the use of energy efficient power adapters. The 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.
