Home / PoE switch interface is broken
The repair process includes checking switch PoE settings, ensuring they are enabled and configured correctly, and updating firmware to the latest version. Additionally, users are advised to avoid working on live devices unless fully aware of safety protocols. This document describes how to troubleshoot Power over Ethernet (PoE) on Catalyst 9000 PoE-capable switching platforms. 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. However, when PoE fails, it can disable critical infrastructure like IP phones, wireless access points, and security cameras.
