Alcatel Unleashed

I am swapping out some of these for customer and before shipping back must return to factory config. Need some guidance on how to complete these steps. Is this done through boot loader sequence or by removing bof files ??

Thanks Andrew

Upload a blank file over the config file referenced in the BOF for both CSMs.
Or change primary-config in the bof to point to a non-existent config file then sync the bof.
Or use file vi to edit the current configuration and remove all the commands and sync.
