Hi,

Usually, the power supplies are configured in redundant mode, meaning the switch uses the first power supply that powered up the system and uses the second one when the first one goes offline. I am not sure if there is a command that shows which one you are using.

You can use the show environment power all to check, if you have redundat power supplies they will automatically switchover in case of failure or power disconnection.
