Case Study: APs Restart Occasionally
Symptom
AP7050DEs connected to a switch restart occasionally.
Relevant Alarms and Logs
The message "PD Over Current indication" is displayed on the switch.
Cause Analysis
The message displayed on the switch indicates that it does not support PoE+ and cannot provide power in compliance with 802.3at for AP7050DEs.
Procedure
Use an external PoE injector that complies with 802.3at and supports the 48 V power supply to ensure that the AP7050DEs work properly. Alternatively, replace the power module on the switch with a PoE+ power module.
Suggestion and Summary
Power supply standards required by APs vary depending on AP models. Therefore, the power adapter or PoE injected delivered with an AP must be used to supply power to the AP. For power supply standards supported by APs, you can query the specifications on Info-Finder.
