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 PoE
- Overview of PoE implementations
- Detection
- Classification
- Inrush and power-up
- Operation
- Maintain power and disconnect
- PoE state-machine diagrams
- Magnetics
- Isolation, PCB design, and safety
- Surge testing and protection
- Lab skills, thermal management, and decoupling
- N-pair power delivery systems
- Auxiliary power and flyback design
