PLANET GSD-504UP is the smallest unmanaged Gigabit PoE switch equipped with two 802.3bt PoE++ ports, two 802.3at PoE+ ports and one uplink port. With a total PoE power budget of 120 watts and non-blocking data switching performance, the GSD-504UP can fulfill the demand of sufficient PoE power for different applications. Complying with the IEEE 802.3bt Power over Ethernet Plus Plus technology, the GSD-504UP provides up to 90 watts of PoE output power, tripling that of the earlier 802.3at plus. With the Legacy function enabled via the DIP switch, it can be backward compatible with 802.3af/at PoE standards to allow users to flexibly deploy standard and high powered devices simultaneously with no need of software configuration. With data and Power over Ethernet from one unit, the GSD-504UP can reduce cable deployment and eliminate the need for dedicated electrical outlets on the wall, ceiling or any unreachable place.
