Hi,
I recently bought a Home Assistant Yellow POE board & followed the setup installation guide for my compute mod5, However the board will not power up via POE. Tried various cables but remains dead. same cables work fine with raspberry Pi3 & home assistant
Does the yellow board come with any warranty?
If the pre-installed CR2032 battery is dead, Could that be why I cant get the solid red power indicator light on the board? The HA Yellow is not even discovered via USB
Simple test would be to try to power via the power jack with a 12 VDC power brick. That would help determine if PoE was bad.
The CR2032 battery is probably only for RTC, so the device will just come up with the wrong date. Probably around new year 1970.
Regarding PoE, then make sure your PoE is the right one for the device. It might require PoE+ or PoE++
Tried a 12v psu for trouble shooting but remained dead, jumpers set to class4 as my Netgear GS724TPv3 switch is PoE+
I since sent back to PiHut that said they would test it , but they’ve now refunded me so guess they came to the same conclusion. I see more posts on the forums about issues with CM5.
