BCM400, 3.7 software, 2/6 split, PDD. Bus 2, 3, 4 have DSM32+ cards with correct dip switch settings. Bus 5 has a DSM32 (no +) card, also with correct dip switch settings. I can only get the first 16 ports to work on the DSM32 (no +). The second 16 ports just continually flash. DSM32 card is in the expansion cabinet. No problems with the other cards in the main cabinet. Any ideas...anybody...anybody???
