RE: Potential heating problem with standard patch Cat5 panels
Depending on PC board thickness, dielectrics, and the possible
presence of ground planes, it is possible that someone might have
built a patch panel with traces as small as 4-5 mils.
Since there has traditionally not been a mandate to support 350mA
of current, this is not a spec violation and constitutes a dilemma.
At a minimum, we should try to determine the installed base of
patch panels and their characteristics to ensure that exposure
(for the general industry) is low. Does someone have market-share
data / technical data for such things?

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.
