Trying to stack 2 3650 switches and one member stuck in initializing, looks like IOS issue, seems they have different versions, but one seems way off and not sure if its reporting correctly?
* 1 52 WS-C3650-48PS 03.06.06E cat3k_caa-universalk9 INSTALL
* 2 52 WS-C3650-48PS 16.3.5b CAT3K_CAA-UNIVERSALK9 INSTALL
the second one is the one that will stay in initialization. not sure how two switches purchased together could be that far off.
