It seems the problem is related to this "Chassis 2 reloading, reason - Active/standby selection failed in 1+1 Mode"

There is a proposal solution on this link

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9300-series-switches/212912-catalyst-9000-switches-booting-to-switch.html

Solution

Unset the Stack 1+1 variable. After this switch is able to boot normally.

just change the variables accordingly

switch:unset STACK_1_1

switch: set

Interesting. Does this mean that when a switch that was previously in 1+1 mode is joined to a stack that is in normal N+1 mode, does not boot or join the stack ?? I cannot find much information on cisco about interoperability of these two modes. What happens when an N+1 is added to a 1+1 stack ? i guess nothing, he will join as a member. But what happens when a previous 1+1 is added to an existing N+1 stack ??
