The DGS-1024A 24-Port Gigabit Switch offers an economical way for SOHO/SMB to deploy an energy-efficient switch that features the increased bandwidth of Gigabit ports. Using a compact desktop style housing helps generate heat dissipation levels that allow for a fan-less design, making this switch silent, as well as economical. This switch helps you conserve energy automatically through several methods. It automatically powers down ports that have no link, allowing the switch to save substantial amounts of power by cutting power usage for unused ports or any ports connected to computers that have been shut down.
