Centralized Power Distribution for Ethernet Networking

The GSD-908HP, a new member in the PLANET 802.3af / 802.3at PoE Unmanaged Gigabit Ethernet Switch family, is an 8-port 10/100/1000T 802.3at Power over Ethernet + 1-port 10/100/1000T Desktop Switch with a total of 120 watts of PoE budget, which is an ideal solution to fulfilling the demand of sufficient PoE power for network applications with Gigabit Ethernet speed transmission. The eight 802.3af / 802.3at PoE Gigabit ports provide PoE power injector function which is able to drive 8 IEEE 802.3af compliant powered devices or 4 IEEE 802.3at compliant powered devices. The GSD-908HP also provides a simple, cost-effective and non-blocking Gigabit wire-speed performance. It comes with a metal compact housing, suitable for desktop deployment in SOHO office or department network application.
