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?)
we have two switch in site, when shutdown one way power of UPS, all ports of the switch was hang, another switch is ok.
then I done powercycle for the switch, the issue was gone.
I don't know why to cause this? the same issue was appear before, then i done a upgrade IOS for the switch.
please view "show system reset-reason".
Thanks for your support.
Power Usage Summary:
Power Supply redundancy mode: redundant
Total Power Capacity 800.10 W
Power reserved for Supervisor(s)[-] 418.32 W
Power reserved for Fan Module(s)[-] 47.88 W
Power currently used by Modules[-] 184.80 W
Total Power Available 149.10 W
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.
