Thank you for contacting Lennar Home Community.
Hope you are doing well!!!
Thank you for the detailed information you shared,
As per the case description I could understand that your ICX-7150-C12P Switch is stuck, and you tried doing a factory reset and software recovery which did not work,
You don't need to follow the Software recovery guide (this is done when the switch won't boot, or the images get corrupted)
In your case, it may be that the PoE (Power over Ethernet) can be disabled/corrupted/damaged.
Could you please perform the below commands and send us the output for the same?
#show inline power
#show inline power detail
copy flash flash secondary (optional for Routing code issue) – Just for a reference
Please let me know if you have any queries in this regard.
