If installing the LEI into the NT8D37 IPE module, determine the vintage
level model. Certain vintage levels carry dedicated 25-pair I/O connectors
only for card slots 0, 4, 8, and 12. These vintage levels are cabled with
only 16 pairs of wires from each card slot to the I/O panel. Some of the
25-pair I/O connectors are split between adjacent card slots.
Other vintage levels cable each card slot to the I/O panel using a unique,
24-pair connector on the I/O panel. In these vintage levels, the LEI can be
installed in any available pair of card slots. However, because of the lower
number of wire pairs cabled to the I/O panel in the lower vintage level, only
certain card slots are available to the LEI.
See
Table 106 "LEI card - NT8D37 IPE module vintage level port cabling"
for the vintage level information for the NT8D37 IPE modules.
