The Extron IPA T IPA is an IP Link® Accessory Power over Ethernet Inserter that inserts power into LAN cable to remotely power Extron IP Link products. The IPA T IPA is Power over Ethernet, IEEE 802.3af, compliant and offers intelligent operation—it only inserts power when connected to IEEE 802.3af compatible devices. It supports 10/100BaseTX Ethernet only.Power over Ethernet is a technology for wired Ethernet local area networks that allows the electrical current necessary for the operation of each device to be carried by the data cables rather than by power cords. This minimizes the number of wires that must be strung in order to install the network, resulting in lower cost, less downtime, easier maintenance, and greater installation flexibility than with traditional wiring.
