How to troubleshoot AC input failure on H3C Switch?
- JJason NelsonJul 28, 2025
To troubleshoot an AC input failure on your H3C Switch, take these steps: 1. Check that the AC power cord is properly connected between the switch and the AC power source, and that both the switch's AC power receptacle and the AC power outlet are in good condition. 2. Confirm that the AC power source is functioning correctly. 3. Ensure the switch's ambient temperature is within the acceptable range and that the power module has good ventilation. Overheating can cause the power module to shut down as a protective measure.
