Upgrading to ExtremeXOS
See “Software Upgrade and Boot Options” in the ExtremeXOS Concepts Guide for instructions on
upgrading ExtremeXOS software.
Miscellaneous notes regarding hitless upgrade:
● 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." is displayed. An
ExtremeXO
S modular software package (.xmod file) can still be downloaded and installed on either
the active or alternate partition.
● For the BlackDiamond 8800 series of switches, a hitless upgrade to ExtremeXOS 12.4.4 from an
earlier release is not supported and should not be attempted. Use the normal software upgrade
process for these switches.
● Hitless upgrade from ExtremeXOS 12.0 and earlier to ExtremeXOS 12.1 and later is not supported on
the BlackDiamond 12800 switch.
