Switch has no PoE output
If your Cisco switch PoE is not working, the most common causes are an exhausted PoE power budget, a disabled inline power configuration, physical cable faults, incompatible powered devices (PD), or a crashed PoE controller. When a problem occurs with PoE, in most cases, the error symptom can be simply shown as the PoE switch not providing power, and the powered devices will stop. Power over Ethernet (PoE) is a convenient technology that enables network cables to carry electrical power, eliminating the need for additional wiring. However, PoE setups can encounter various issues. Here are some common PoE issues and how to troubleshoot them: 1. To isolate the problem fast, log into the Catalyst switch and run show. Explains how PoE-capable switch identify the power requirement and how PoE works on a switch.

Gigabit Switch PoE Principle
The answer is through the use of phantom power—power sent over the same wire pairs used for data. When the same pair is used for both power and data, the power and data transmissions don't interfere with each other. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points. A PoE (Power over Ethernet) switch is a network switch that delivers both power and data through a single Ethernet cable to connected devices such as IP cameras, VoIP phones, wireless access points, and IoT devices. A PoE switch is a network switch that has PoE injection built-in, eliminating the need for separate power supplies for network devices.
