Can't install ARX board

Is there any intitialization trick to installing one of these expansion boards? I've tried four times, I don't think I have any doubts about the card being seated correctly, but when I power on the 700R nothing happens.  I'm expecting to see something on my computer screen to the effect that the card is being installed or initialized.
 
I probably have a bad card (or bad 700R), but thought I'd ask here first.
 
Thanks.
