This chapter is an overview of recommended use active and passive PoE

The article compares Active and Passive Power over Ethernet (PoE). Active PoE, compliant with IEEE standards, automatically negotiates power delivery between the source and the device, ensuring safe and appropriate power levels. In contrast, Passive PoE delivers a constant voltage without negotiation, requiring manual matching of the power source to the device's requirements. While Active PoE is safer and more flexible, Passive PoE is simpler and more cost-effective for compatible devices, highlighting the importance of understanding the correct and incorrect usage to avoid damage.

Active PoE is standardized, involves power negotiation for precise delivery, and supports a wide range of devices. In contrast, Passive PoE delivers a fixed voltage without negotiation, offering simplicity and lower cost but with increased risk of compatibility issues and potential device damage if not properly matched.
