Overview
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 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 25-pair cable connections. Table 34 on page 262 shows the
cable connections from the backplane to the inside of the I/O panel.
Figure 114 on page 262 shows the designations for the backplane end of the
cables, the backplane slot designations for the cable connections, and the
associated network segments for the backplane slots.
