I have a CIX670 with 4 expansion cabinets. i have a 16port BWDKU in slot 1 of the 1st cabinet where ports 12-16 appear to be dead. i have pulled the card and put back in with no change. My question is can i buy a new BWDKU and just put it in the same slot and all configurations/extension remain or is that info stored within the card itself and the new card would appear as a new configured card?
