I have an ICX 7150-C12P and the PoE has switched off.

I have an ICX 7150-C12P. The power was out for several hours and when it came back on the PoE wasn’t active. I have done the factory reset about a dozen times and I can’t get it back. I’ve read all these complex instructions on finding IP address, using a terminal prompt etc etc etc. Unfortunately all of that is over my head. Is there a way to manually turn it back on? Any help is greatly appreciated.
