Image Types and Image Filename Prefixes

The software image file can be an .xos file, which contains an ExtremeXOS core image, or an .xmod file, which contains an ExtremeXOS modular software package.

Filename Prefixes

You can identify the appropriate image or module for your platform based on the filename prefix of the image.
