Using the CLI and setting an interface range then executing   "power inline never" and then "power inline auto"  the power status will change to "on" and the POE devices will power up. Maybe antoher solution exists.
I have two N3024 switches in a stack.  The switches have been up for several months.  The AP has only been connected for a couple of weeks. Originally, on the power status, from the show power inline CLI command, unit one was on and unit two was off.  I was never able to find a command to turn the power on unit two. I have one POE AP connected to unit one. Early in the morning of March 11th the AP lost power.  Now the power status for unit one is off and I can't get any POE device to power up from the switch.   Is there a command that will turn the power on?  What would cause the power to be turned off without some one specifically shutting it off.  What can I do to troubleshoot?   The power management mode was originally Dynamic and I changed it to Class to see if that made a difference. The AP will power up if I use a power injector, so I don't think the problem is with the AP. The unit status from the CLI command is below.
