17. After the stack resets, verify the new firmware has become active.
18. Select System > File Management > Active Images again.
19. Notice the new firmware (i.e. 4.2.0.4) is now the Current-Active image for each member.
Note: While downgrading to a previous firmware is supported, all features and functions that were not
part of the previous firmware will be lost, including those features and functions that were introduced
in the current firmware in use. Firmware version 4.2 or later must be active on all stack members in
order for stacking to work. Do not downgrade a stack to firmware version 4.1.x.x or earlier.
Un-Stacking (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 a member 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
