Upgrading to ExtremeXOS

For instructions about upgrading ExtremeXOS software, see "Software Upgrade and Boot Options" in the ExtremeXOS User Guide. The following are miscellaneous hitless upgrade notes:

• 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.
• SummitX software is required for E4G cell site routers.
• Beginning with ExtremeXOS 15.4, a limited hitless upgrade procedure is supported on the BlackDiamond X8 and BlackDiamond 8800 series switches.
• For Summit X480 series switches, starting with ExtremeXOS 15.6, two separate software image files are used for both individual switches and stacks that include Summit X480 series switches. For more information, see ExtremeXOS Images for Summit X480 Series Switches.
