RE: Potential heating problem with standard patch Cat5 panels
Hi Rick,
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?
Regards,
Dan Dove

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.
