Thunderstorm caused PoE switch to fail

Specialty cable knowledge brief Published 18 Oct 2024

Prepared for preliminary research by the ZITHA SPECIALTY knowledge desk. Confirm fire performance, mechanical protection, loss budgets and installation requirements against current standards and product documentation.

Firmware Updates: Ensure the switch firmware is up-to-date to fix any known issues. This is a place to discuss all things Ubiquiti, especially UniFi. Since upgrading the a Switch Pro 24 POE (previously had a Switch 16 POE) I've had 2 thunderstorms in my area. Both times the POE has gone out the switch. This document describes how to troubleshoot Power over Ethernet (PoE) on Catalyst 9000 PoE-capable switching platforms. Cisco recommends that you have knowledge of these topics: • Catalyst 9000 Series switches • Power over Ethernet This document is not restricted to specific software and hardware. 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. The cause of failure may be attributed to many factors, including hardware device factors and software factors. 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.
