The switch is not powered by PoE
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 working. Despite its convenience, PoE can sometimes fail or behave unpredictably, causing devices to lose power, intermittently disconnect, or fail to start. This article provides a detailed, step-by-step troubleshooting guide focusing on Cisco Catalyst 9300 switches, supplemented by general principles. However, when PoE fails, it can disable critical infrastructure like IP phones, wireless access points, and security cameras.

Connecting non-PoE powered devices to a PoE switch
The connection method is: Non-PoE switch → (network cable) → PoE injector → (network cable) → PoE terminal. Ideal Match: After connecting, the standard PSE and PD will negotiate via hierarchical or LLDP protocols. And what happens if you accidentally plug in a normal (non-PoE) device into a PoE switch? I explore all this – and more – in this video. It allows compatible devices, such as VoIP phones, network surveillance cameras or wireless access points to work in places where power outlets or network connections don't exist. PoE is a straightforward technology that transmits power and data via the same network cable to the powered devices.
