Who Me Too'd this topic

Hi everybody,

I have a trouble with a switch (switch 1 master of  3 switchs in one stack)  that is rebooting continuously when i connect a machine on it.

Historic:

I rebooted the stack because of electric cut.

After startup completed, the switch 1 master rebooted again and again

I turned off the switch 1 and I downgraded the priority level

I powered on the swtich and it has been added to the stack with slave position.

If i don't connect PC on it, it's ok but as soon as i connect a PC, the switch is rebooting

When i connect or remove a PC on the switch, it reboot with logs below:

When I remove the switch of the stack , I have the same issue if I connect a PC.

I don't see warnings for hardware failure.

I have crash info but i don't know how to translate it?

Do you have any idea?

Reinstall the IOS?

Thanks in advance for your help
