No PoE switch power supply
Try using a DC power supply and a passive injector to power the circuit, run it at 52V. 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. 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. The device does not receive redundant power when it is only connected to the PoE port. Cisco Discovery Protocol (CDP) with power consumption: The powered device notifies the device of the.
