Red light beeping and chirping when carrier board is plugged in?

I have the following Leopard Imaging carrier board plugged in:

And two cameras attached. But when I plug in the unit, the red LED beeps and chirps at me! If I take off the board the TX2 works normally.

If it makes any difference, I also have a Samsung SSD attached as well (but removing that disk had no effect).

Is this a power draw issue? If so, how do I fix? I know this configuration should work.

Never mind. I was plugged into the wrong expansion connector.
