PoE Switches - what are they, when to use them, what to know about them, and when not to use them.

Power over Ethernet is a valuable technology that provides significant benefits for modern networking, including simplified installations, reduced wiring costs, and enhanced flexibility in device placement. The development of new standards, such as 802.3bt, is expanding the range of applications. Choosing the right PoE implementation (switch vs injector) and power class/standard for your needs requires a proper understanding of the technology's capabilities and limitations. Careful planning is necessary to ensure adequate power delivery and to mitigate potential issues associated with a central point of failure.
