I feared the worst. I was struck by how cheery the lady was. I had my hardware guy exchange the card. Unfortunately, the cards were back-ordered and they took about two more weeks to give me my new card. I have to say that I was quite annoyed at this, since I was anxiously chomping at the bit to get this thing up and running.
Some people have problems with ports past the first eight.
I have tested my card up to port 11 and all the ports appear to be working. I suspect that if I'd exchanged the card directly through the factory I would have had better service than through my dealer. The factory people were all quite nice and eager to please. Right now, I have only four phone lines. If you've found this FAQ helpful, or if you have more information to add, I'd enjoy hearing from you.
