All, I'm hoping I haven't run into an issue that can't be overcome.
I have used the POE board a few times for remote sensing and not had any issues.

A current project requires an LCD display for feedback to the user.  The LCD I have requires SPI.  I didn't have the normal SPI pins I usually use for the LCD but I did configure it to use the following.  And you'll be glad to know that yes the LCD works.

When I then combine it with the ethernet it kills the ethernet.  As far as I can see they are NOT using the same SPI bus but I am not overly familiar with the ethernet setup.

I will look into SPI bus contention but ideally with chip select you should be able to do this.

If anyone has any information that would help save me time on where I shoudl look please help!  If not I'll update the post with whether or not this was possible.
