Brad,
We got it working correctly with the heatsink according to the attached
drawing. No fan. It works in the Dutch circumstances, which is
seaclimate. Summer is app. 30-33 deg C max.
The aluminum part at the back off the plastic enclosure that was made
for us has been enough to cool the board.
Regards,
Wim Bos

Subject: [Karlnet] KN-100 Dimension and Cooling Questions
All,
Does anyone have a copy of the KN-100 "User Guide"? Does it give any
more
dimensional information on the board itself than the Integration Guide
does?
Specifically, I'm wondering how much space exists between the bottom of
the inserted PC Card and the top of the processor? Is there enough room
for a low profile (0.25" tall) heatsink on the CPU?
What are the heat related issues with using this board? I've read in
several places about PoE voltage causing issues, is the high PoE input
voltage the only heat related issue, or is processor and card heat
dissipation a real concern as well? Under what circumstances are a fan
required, and where are they mounted on factory fan-cooled units (is
there
such a thing)?
Reason I ask is that I'm soon going to be trying out an all-in-one PoE
flat panel antenna solution with a KN-100 internally, and want to make
absolutely sure it does NOT cause me any undue temperature related
grief.
FYI, I'm in the upper midwest, where our ambients can range from -20F in
the winter to +100F in the summer (hotter in the enclosure to be sure).
I'm a huge fan of "bulletproof" vs. "it works, don't fix it", and gladly
go to the extra engineering and fabricating effort to ensure it.
Thanks in advance!
Brad
