Optimal Solution for Energy Savings and Gigabit High Performance            PLANET GSD-504 Green Networking Switch is specially designed to meet the current trend for energy savings worldwide. The GSD-504, a 5-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-504 uses new engine that provides power savings of up to 40% but maintains high performance efficiently. It incorporates two advanced Green Networking technologies: Hibernation Link Down power savings Intelligent use of power based on cable length   The Hibernation Link Down power savings 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-504 will automatically adjust power usage of the ports that are shut down or not connected to network device.  Intelligent use of power uses an intelligent algorithm that actively determines the appropriate power level based on cable length. When the GSD-504 is connected with Ethernet cable shorter than 20m, a device can obtain maximum power savings because the GSD-504 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. Leading Home, SOHO and Workgroup Users to High-speed Networking Generation The GSD-504 is designed with modern plastic compact housing and easy to deploy high speed Gigabit networking in home or SOHO applications.  Providing 10Gbps internal switching fabric, the GSD-504 can handle an extremely large amount of data in a secure topology linking to a backbone or high capacity servers. The GSD-504 provides 2K MAC address table, and wire-speed packet transfer performance without risk of packet loss. The high data throughput of the device makes it ideal for most Gigabit environments, especially for the network to be upgraded to a Gigabit environment.   Plug & Play All RJ45 copper interfaces of the GSD-504 support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ45 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-through or crossover cables.
