[Soekris] JP10, DC Power Connector

[David Dudley]

The documentation in the Net4801 manual says that you can directly feed
+5 into pin 4.  What I'm wondering about is whether I should also feed
+12 into pin 3.

You should double check with Soren before you feed anything into the
5V
pin, I don't know if the PSU circuits will like that.

You can feed the board on the 12V pin, (same V-range as on the DC
plug) which I belive is _after_ the input protection circuitry, so
JP10 is not reverse polarity protected.

Never attribute to malice what can adequately be explained by
incompetence.
