I swapped out the 3 .54 cards with some older rev ones, and within a day two of them were missing some channels, argh! I guess it's not the NACs. I had forgotten about the NIC's, they were still the ones that came with the .54 cards (rev d), so I swapped them out with older ones (rev c), we'll see what that does. Question for anyone: Does the NIC contain any non-volatile storage? For example, if you set a UI password, does the password follow the NIC or the NAC?
