Hi,
I have a stack of 8 3750x switches connected via Stackwise. In addition, I have these switches configured as two Powerstacks. When I look at the Powerstacks, they are showing as being in power-sharing mode. When I look at the individual switches, they show as standalone. Right now, I have 1 switch in each powerstack that has two power supplies, and then the other three have a single power supply. Below is the output for "Show stack-power detail" as well as the Powerstack configurations.

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
