Looking for other people experiences and reporting my test results below.
First tests who that auto stacking is pretty cool and works well.
I stacked a single X450-G2 and let it run. I then connected a second X450-G2 with stack cables and powered it on. The stacked switched added the second switch to the stack and upgraded the firmware to match what was installed on the master.
Next I unplugged the stack cables and connected the master to a different X450-G2 to simulate replacing a failed slot. The master added the new switch as slot 2 and upgraded its firmware just as it did with the first switch.
Unfortunatly adding a trial license to the master switch causes the second switch to come up with a role of “none” I had hoped it would make the second switch a standby node that could easily have its license upgraded…
Do we know the expected behavior in case of a license mismatch?
