Hi
did u try pulling out and re-inserting the SUP card back on the slot ?
the logs tells that active sup was in slot 2 earlier which is down and non operational.
Coz of the same the sup in slot 1 has become active sup now.
i would suggest to take out the sup card and re-insert the same again or try in someother slot (may be in 3rd slot)if u have some free slots available over there in your chasiss.
