Hi kozyrevdik,
Can you sftp to the switch? then download /var/log/messages.
it will record the issue in the message file.


Unfortunately, it is only possible to connect via a com port and only the boot menu is available
The switch no longer responds to any commands

If you can’t access the switch with SFTP, I think you need RMA the switch.
