Publisher's Note: Products purchased from Third Party sellers are not guaranteed by the publisher for quality, authenticity, or access to any online entitlements included with the product.A Complete Guide to Transmitting Electrical Power and Data over Ethernet Cables
Power over Ethernet Interoperability explains how to safely transmit DC power over an existing data network cabling structure so that separate AC electrical wiring is not needed to power up devices connected to the network. With a focus on cost-effective unshielded twisted pair (UTP) cables, this book provides proven methods for designing reliable Power over Ethernet (PoE) equipment and ensuring that it functions effectively. Details on the IEEE 802.3af/at standards and how various devices can operate from PoE are also contained in this practical resource.
Coverage includes:The evolution of PoEOverview of PoE implementationsDetectionClassificationInrush and power-upOperationMaintain power and disconnectPoE state-machine diagramsMagneticsIsolation, PCB design, and safetySurge testing and protectionLab skills, thermal management, and decouplingN-pair power delivery systemsAuxiliary power and flyback design
