with standard patch Cat5 panels
From my personal experience, a 12
degree C rise is trivial and would not cause any
PC board discoloration, unless the PC board was operated
above 100 degree C.
Or the PC
board material is faulty. I wonder if it is FR4.
If the patch panels are being
damaged, there must be a whole lot more current involved than 350ma,
or the traces are very thin, or it
has a different cause.
