JES, problem identified! The culprit is the control board, looks normal, there seems to be some problem in or out coming signals to the net,it does not identify itself on a IP scanner. changed inbetween the healthy one an d the bad one, so no problem with the hashboards. Awesom was inndicating 44 of 66, wich is wrong as there is only 44 chips on each board. Bitmain has produced several models of the T17+ this particular one has 58Th, so the Awesom FW got confused. Regardind the control board it may just be something with RJ45 connector, but i think its easier to just get a replacement board?

I open up another one, a T17 it had actually a heatsink off! there is some videos in Russian language, about fixing this, but i semm not to understand if the chip is replaced or resolderd? i should be burnt shortly after heatsink falling off, while in mining mode? Isnt there a way to just "short" the bad chip out and thus restoring integrety of the chain?
