Extends an existing Power over Ethernet connection beyond the 100 m (328 ft.) limit Saves time and money by delivering data and power via existing network cables Covers longer distances by cascading multiple PoE extenders (Model 561211) together Can be daisy-chained with up to four PoE extenders for a distance of up to 500 m (1640 ft.) Supports 10/100/1000 Mbps data rates and delivers up to 25 W to a connected PoE device PoE awareness ensures that power is only sent to IEEE 802.3af/at-compliant devices; non-PoE devices only receive data Requires no additional power supply; draws the power directly from the PoE input Compatible with IEEE 802.3at/af-compliant PoE injectors and PoE switches (PSE) Compatible with IEEE 802.3at/af-compliant powered devices (PD)
