Solved: AP1852E rebooting loop

Tehnic2 Vetro · ‎08-20-2023

I have an Cisco AP1852E that is entering in rebooting loop and the message is: "SMP: failed to stop secondary CPUs"

- Try factory reset of the AP , if the same log type is seen afterwards , then the AP might have a hardware problem and needs replacement (RMA) ,

Save the entire AP console log from power on to a text file and then attach it here so we can see all the logs?
