Cisco Logs

Good Afternoon,

Newbie here. I ran into an issue with 4 stacked Cisco 3850’s where the 4th switch was displaying amber lights and connected machines were not getting any connectivity. I had to manually power down all for devices and restart. Eventually performance returned, but now I would like to perform a Root Cause Analysis and need to know if there are logs I can review to determine to cause of the switch hanging.

Does anyone know if this is possible and what to do to retrieve these logs.

Thanks!
