After working with Netgear support, they idenfy this to be a hardware issue specifically with the power module.
The switch’s PoE subsystem is failing to initialize at boot. Evidence from the technical logs shows: ⦁ PSE remains OFF and “Get PoE FW Failed” is reported. ⦁ show poe port info all returns only headers (no port table), which occurs when the PoE controller is not up. ⦁ No OS/kernel crash dump is present; system uptime and boot logs are otherwise normal aside from transient driver buffer warnings. ⦁ Thermal and fan readings are normal; PS‑1 and PS‑2 are operational (PS‑3 not powered is non‑blocking).
Just putting out there for anyone facing a similar issue. Keep in mind any warranty for your hardware.

Had ever connected the console as suggested earlier?
One would expect these problems as also recorded in the tech logs would become visible.
