575C card

Tried placing a 2 slot RAID card with a label on it that says 575C into my
8203. At first, under the BP's recommendation, I tried putting it in the
CEC in the last two slots. But I couldn't figure out how to fit that blue
carrying handle into the back plane. It goes off at an angle and the
objects in the back didn't. I did remember to pinch the two terra cotta
things together and lift the little flap but that didn't help.

So, the BP said I should be able to fit it into an 0595 into slots 3 and
4. One of the cards show up as only Occupied but the other shows up as
575C. On the HMC C03 shows up allocated to that lpar but Unknown. It
doesn't work.

On another rack containing one of these cards it looks more like:

I did the installation with the entire rack powered off. Both slots are
allocated to the same lpar.
