PLANET GSD-803 Green Networking Switch is specially designed to meet the current trend for energy savings worldwide. The GSD-803, an 8-port Gigabit Ethernet Switch, brings both benefits of energy savings and Gigabit wire speed performance to home networking, SOHOs and enterprises. Energy Savings - The GSD-803 incorporates two advanced Green Networking technologies and can provide power savings of up to 40% but maintains high performance efficiently. (1) 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 use of power uses 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 savings 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 savings. 8 x 10/100/1000Mbps Gigabit Ethernet ports Complies with IEEE 802.3, 10BASE-T, IEEE 802.3u 100BASE-TX, IEEE 802.3ab 1000BASE-T Supports auto MDI/MDI-X function Hardware based 10/100Mbps, half/full duplex and 1000Mbps full duplex mode, flow control and auto-negotiation Features Store-and-Forward mode with wire-speed filtering and forwarding rates IEEE 802.3x flow control for full duplex operation and back pressure for half duplex operation Integrated address look-up engine, supporting 4K absolute MAC addresses 9K Jumbo packet size Power saving ability for Green networking Automatic address learning and address aging Supports CSMA/CD protocol Made of metal, desktop size and wall-mount design LED indicators for system power, per port 1000 & Link/Act 5V DC, 1A external power adapter FCC, CE Class B compliant SEE TECHNICAL DATA SHEET FOR FULL DETAILS
