[Soekris] Temperature Issues

[selfabuse@selfabuse.net]

Hello,
I was hoping I could rack everybodys brain here for a moment. I have a
net4521 that is currently acting as a wireless AP for the corporate park I
work in. It's mounted in a NEMA enclosure out in the center of the park.
I'm up in PA, and it's started to snow over the past week - Temperatures
at night have been in the single digits (Farenheit). From about 5:30pm to
about 9am all our wireless customers keep bouncing up and down. As best I
can tell, it's because the temperature drops below the recommended
operating temperature for the board. Does anyone have any experience with
keeping these little guy heated? The whole setup right now is running off
of a 12v deep cycle battery, so adding a heater isn't really an option. We
were thinking of putting it in a smaller plastic enclosure inside the NEMA
case and finding some kind of temperature monitor that would run on it,
and kick on a little 12v dome light to heat up the plastic enclosure when
the temperature hit about freezing. I just wanted to see if anyone else
has run to similar issues so I don't duplicate efforts.

Thanks!

Regards,
Ross Logan
