Hello Richard,
Can you describe the problem in greater detail? I do see (in the logging log) that power supply 1 is
going down...have you figured out why that's happening? (e.g. do you have a power source issue?)

Ken

Thanks for sharing the power mode (being redundant, there *should* be no impact to the switch when 1 power
supply fails or loses power).
I did a quick search for any known matching bugs, but didn't find any.
I'd advise opening a TAC Service Request for furhter analysis and to determin the root cause of the hang.
Regards,
Ken
