Power over Ethernet (PoE) is a technology for the delivery of power and Ethernet data on the same cabling. PoE technology saves time and the cost of installing separate power cabling, ac outlets and wall warts, and eliminates the need for a dedicated uninterruptible power supply (UPS) for individual devices.
The power delivered over the Ethernet infrastructure is automatically activated when a compatible terminal is identified and blocked to non-compliant devices, such as desktop computers and laptops. This lets users freely and safely mix non-compliant and PoE-compatible devices on their network.
The POH-1250 is fully compliant with the IEEE 802.3af standard and acts as a patch panel between a switch and other network devices to provide power and data, and it supplies PoE power of up to 15.4w per port over existing Cat.5 Ethernet cable.
