Hi Team,
I have installed and configured cisco 3750X series switches in stackwise. Those are having dual power supply.
Power redundancy test performed:
1. Removed one of the power supply and inserted it back.
2. once the first power supply is ready, removed another power supply and switch got rebooted.
please find the below stack-power output:

Can anyone help what went wrong here?

Stack topology: Standalone
Never tried this before but this could be it.

I have checked the other stack where power redundancy is working fine and it has stack topology:standalone only. But it has stack mode: Power Sharing strict thats the difference.
Really Wierd!!!

I had the same thing happen when installing a new stack. One of the switches went into "Standalone" mode. All you have to do to get it back into the powerstack is do the following:
conf t
stack-power switch x
no standalone
end
Remember you'll have to manually assign all of the switches in the stack to a Powerstack because the default that it does to a large stack (> 4) isn't what you'll probably want.... as you saw.

Cosmetic bug
CSCui21029 3750X Stack no standalone stays in running configureation as standalone
Symptom:
When you are configuring a 3750x stack and initially putting it into a stack ring topology by configuring the following.
Switch(config)#stack-power switch 1
Switch(config-switch-stackpower)#sta
Switch(config-switch-stackpower)#no stan
Switch(config-switch-stackpower)#no standalone
You will see that in the running configuration it shows up as standalone mode
stack-power switch 1
switch mode: standalone
stack-power switch 2
switch mode: standalone
Conditions:
3750X stacks with any license level
Workaround:
none
