Energy Saving
The GSD-803 incorporates two advanced Green Networking technologies and is able to provide power saving up to 40% less energy but maintains high performance efficiently.
(1) Hibernation Link Down power saving
The Hibernation Link Down power saving goes beyond IEEE specifications to automatically lower power for a given port when it is not linked. With the Hibernation Link Down power saving technology, the GSD-803 will automatically adjust power usage of the ports that are shut down or not connected to network device. 
(2) Intelligent scales power based on cable length
Intelligent scales power, the other technology adopted, is an intelligent algorithm that actively determines the appropriate power level based on cable length. When the GSD-803 is connected with Ethernet cable shorter than 20m, a device can obtain maximum power saving because the GSD-803 would automatically detect the Ethernet cable length and diminish power usage. The connected device can substantially reduce the overall power consumption, which makes a significant contribution to energy saving.

Plug & Play
All RJ-45 copper interfaces of the GSD-803 support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ-45 Category 5, 5e or 6 cables. They support standard auto-MDI/MDI-X feature which can detect the type of connection to any Ethernet device without requiring special straight or crossover cables. 

Home/SOHO High-speed Network Center
The GSD-803 Gigabit Ethernet Switch provides the best solution of high-speed Internet environment demanded by SOHO / Home and Power users. The GSD-803 accelerates the speed of data transmission between devices without worrying about the delay of high quality multimedia display. In aspect of home use, the GSD-803 integrates the speeds of 10, 100 and 1000Mbps which can fulfill your demands of transmitting high quality multimedia, games and other high-speed Internet applications.
