Find the reason a switch rebooted

[fmoghimi]

Hi

I have a switch stack of two 2960x switches and the it rebooted on 9/11.

How do you guys find out the reason that the switch rebooted?

I only have a crashinfo file for the 7th September and it's kind of difficult to understand this file.

I doubt that the file from 7/11 has anything to do with the reboot on 9/11.

Any help is appreciated, thanks in advance!

show version give you reason, but old Logs will be deleted (if you have any syslog server can view what is wrong?)
