And another thing. Is this a CPU issue, a PoE issue, both? I'm trying to narrow down where to look on the board for problems. So often these are easy to fix. I have a few caps (but they are near the power supply) that are measuring as shorted so possibly there is one bad one somewhere (could also be normal). I may need to remove the heat sinks but then I'll probably also need to replace the thermal pads... Anyone else do SMD rework here? I'm not very familiar with the 7450 topography so I am looking for help on where to look on the PCB. The way I read the diagnostic error is that watchdog is restarting or shutting down one core of the CPU?
