For WS-C4500X-32SFP, I would like to unplug the power cable one side at a time and reboot.
If you leave the Active side, I think that the Stanby side will also be restarted.
To do this, first unplug the Stanby power cable.
Get up, make sure you're in HA, and then Stanby is Active.
I think that if you disconnect the power of the original Active side, you can restart both of the units, but how about the procedure?
