Click OK if prompted with the above screen. Rebooting the stack may take a few minutes longer than a
single switch. After reload, the firmware upgrade is complete. To validate each switch, login again to
the Web UI of the stack Master, and then go to System > File Management > Active Images.
Notice that as the backup versions become active, the previous active versions now become the
backup. This allows the administrator to toggle back to the previous image if needed for
troubleshooting. Going back to the previous version is rarely ever used and must be done with extreme
caution if the newer firmware has been running a long time with several configuration changes since
the initial upgrade. Newer firmware can have dozens of valuable bug fixes that will not be there on the
older firmware.
Removing member units
This section provides guidance on how to remove member units from a stack while minimizing traffic
flow interruptions within the stack. Removing any member of a ring topology stack does not require a
reload of any member unit in the stack.
If a unit in the stack fails, the Master unit removes the failed unit from the stack and no changes or
configuration are applied to the other stack members; however, the dynamic protocols will try to re-
converge as the topology could change because of the failed unit. When there are no connected ports
on the failed unit, the stack will be intact without changes. The example below demonstrates how to
manually remove a single member while keeping the stack intact.
