I've seen the sup reset cards after is saw "a problem", but not leaving them in a powered off state.
Normaly the sup should know why it has turned off power.
Hopefully you took a sh tec on the console before resetting? If not we will probably never know what happened.
Maybe cisco is willing to swap the sup or the chassis, but there is no clue to what is the source of the fault.
Cheers,
