ePMP 4625 Reset Via Power Sequence

Can someone confirm the Reset Via Power Sequence actually works. We had the need to reset a few units and were forced to take them down and reset via the reset button. No combination of power on/off would reset them for us. We never changed the default setting for Reset Via Power Sequence but can’t confirm it was not disables because we were not able to gain access of these units.

I can confirm that it works in the lab for me.
Thanks

Can you access them using the default of 169.254.1.1?
