Appendix B: Cable description and NT8D81BA cable replacement
This section explains how to replace the NT8D81BA cable with the
NT8D81AA cable and how to install the NTCW84JA special IPE filter.
Cables are designated by the letter of the I/O panel cutout (A, B, C, and so on)
where the 50-pin cable connector is attached. Each cable has three 20-pin
connectors (16 positions are used), designated 1, 2, and 3, that attach to the
backplane. Using the designations described, the backplane ends of the first
cable are referred to as A-1, A-2, and A-3. The locations of the cable
connectors on the backplane are designated by the slot number (L0 through
L9 for NT8D11, L0 through L15 for NT8D37) and the shroud row (1, 2, and
3). Using these designations, the slot positions in the first slot are referred to
as L0-1, L0-2, and L0-3.
In NT8D37BA and NT8D37EC (and later vintage) IPE modules, all 16 IPE
card slots support 24-pair cable connections. Table 77 on
cable connections from the backplane to the inside of the I/O panel.
