PLANET SWITCH GSD-503

Optimal Solution for Energy Saving and Gigabit High Performance 
PLANET Green Networking Switch - GSD-503 is an ideal solution in line with the energy-saving trend worldwide. The GSD-503 is a 5-port Gigabit Ethernet Switch bringing both benefits of energy saving and Gigabit wire speed performance. It is specially designed for home networking, SOHOs and enterprises. 

Energy Saving
The GSD-503 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-503 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-503 is connected with Ethernet cable shorter than 20m, a device can obtain maximum power saving because the GSD-503 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.
