As I posted in my last post everything is working fine with your switch.
I also checked the sh mod and it clearly states first sup is in active and second in standby state.
If you reset the active sup definetely the standby sup will become active and console is active only on active sup.
If your sup in slot 1 is active console will work for that and console for sup in slot 2 which is in stadby state will be disable and same if you reset the 1st sup which is active it will become standby and standby sup will become active and from then onwards the console will start working.
Remember console port only works with active sup.
Also I think when you run the command"sh redundancy state" you will see one sup in active and second su is standby cold state which mean it is working in way which it should be.
