Beginning with ExtremeXOS 12.1, an ExtremeXOS core image (.xos file) must be downloaded and installed on the alternate (non-active) partition. If you try to download to an active partition, the error message Error: Image can only be installed to the non-active partition. appears. An ExtremeXOS modular software package (.xmod file) can still be downloaded and installed on either the active or alternate partition.
