Hello ,

to understand if the issue is on the standby supervisor or on the C7600S chassis you would need a maintenance window of two hours:

you power off the chassis and swap supervisors in slot 5 and slot 6

You then power on the chassis and look at the results:

I see four possible cases:

a) the supervisor now in slot5 keeps rebooting --> the issue is on the supervior --> open an RMA for it

b) the supervisor now in slot 5 is stable, but the supervisor in slot6 keeps rebooting ---> the issue is on the chassis it is rare but it can happen

c) both swapped supervisors are stable.  At this point I would swap again after a power cycle.

d) both swapped supervisors are not stable.

What about power usage in the chassis? there is enough power for all linecards and the supervisors ?

Hope to help

Giuseppe
