To fulfill the demand of sufficient PoE power for network applications with Gigabit speed transmission, there is a new member in the 802.3af PoE Gigabit Ethernet Switch family -- GSD-804P, the 8-Port 10/100/1000Mbps with 4-Port 802.3af Power over Ethernet Switch which features high performance Gigabit IEEE 802.3af PoE (Up to 15.4 watts) and totally 55-watt PoE budget on half of the 10/100/1000Mbps TP ports of GSD-804P. The four 802.3af PoE ports provide PoE power injector function which is able to drive 4 IEEE 802.3af compliant powered devices. The GSD-804P also provides a simple, cost-effective and non-blocking wire-speed performance with 10-inch metal shape for desktop deployment in compact housing, SOHO office or department network application.
