PoE circuit of the switch
Standards-based Power over Ethernet is implemented following the specifications in IEEE 802. In multi-pair cases, PoE supplies power as a over two or more of the At its core, a PoE circuit diagram consists of two major parts---the power side and the data side. On the power side, a special transformer reduces the voltage provided from your switch down to 15. The list is not exhaustive, but it does cover every component or component group in flybacks and active clamp forwards (ACF) topologies. This application note provides detailed information and circuitry design guidelines for the implementation of a single port Power over Ethernet (PoE) system, based on Microchip's 1-port PSE PoE controller, the PD69101. The LM5070 HE (High Efficiency) evaluation board is designed to provide an IEEE802. PoE systems have proven beneficial for applications like surveillance cameras, home/building controls, digital signs, VoIP phones within enterprises, and Wi-Fi access points.

Where does a PoE switch get damaged by lightning strikes
Yes, in real-world deployments, especially in outdoor or industrial settings, PoE switches can be susceptible to electrical transients such as lightning strikes or power grid disturbances. These surges can propagate along the Ethernet cable and damage the switch and the devices it. What is the explanation? What can I do to avoid it? Can the lightning enter through the indoor network cabling? Or maybe through some network device not connected to UPS?Today we had a massive thunderstorm coming through and one lightning strike must have hit my house or at least very close by. Core protection: Build a standardized grounding system and install compatible PoE surge protectors at key locations.
