NT5D97 circuit card locations

Each NT5D97 card requires one slot on a shelf. NT5D97 cards can be placed in any card slot
in the network bus.
Note in all cases - If an NT8D72BA/NTCK43 card is being replaced by a DDP2 card, the D-
channel Handler can be reconnected to the DDP2 card, or removed if an onboard
NTBK51DDCH card is used. Also, DIP Switches in the NT5D97 must be set properly before
insertion. NT5D97 has a different DIP Switch setting from NTCK43AB. Refer to
AB DIP switch settings

NT5D97AA/AB DIP switch settings

The NT5D97 DDP2 card is equipped with 6x2 sets of DIP switches for trunk parameters
settings for port0 and port1 respectively. Additionally, the DDP2 card is equipped with one set
of four DIP switches for the Ring Ground setting. The NT5D97AA/AB has one set of eight DIP
switches and NT5D97AD has two sets of ten DIP switches for the D-channel Handler
parameters setting.
The DIP switches are used for the setting of default values of certain parameters. Firmware
reads the general purpose switches, which sets the default values accordingly.
