Userlevel 6 is ancient, upgrade to something newer (https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-Use-the-Boot-Rom-Menu-to-Download-a...) andf if the error is still there you probably have a broken switch.

Yes, as Oscar said the EXOS is very old and unsupported, please open a GTAC case if you are unable to recover.

Thank you for your update, can I open case through GTAC without having support contract ?
