The DAC can be installed directly into slots 0, 4, 8, and 12 with no cabling
changes. If other slots are required, the upgrade must be made. Follow this
procedure to upgrade your cabling. You can upgrade the cabling
segment-by-segment, or the entire module at one time.
Note 1: Four NT8D81AA cable/filter assemblies are required to
upgrade the entire module, one assembly per segment.
Note 2: Cables are designated by the letter of the I/O panel cutout where
the 50-pin cable connector is attached. The 20-pin connectors are labeled
1, 2, and 3.
Note 3: The locations for the cable connectors are designated by the slot
number (L0-L9), and the shroud row (1, 2, and 3).
