of the available MMI commands.
Installation Because of the wiring in some of the system modules and cabinets, the LEI
only works in certain card slot pairs. These restr ictions depend on the type
of module or cabinet. In all other modules or cabinets where the conditions
listed below do not exist, the LEI works in any two adjacent card slots:
•In the NTAK12Small Remote IPE Expansion Cabinet only card slots
10-15 are available.
•In the NT8D37 IPE module, if the 25-pair I/O connectors are partially
split between adjacent IPE card slots, the LEI works only in card slots
where Unit 0 of the motherboard card slot appear on the first pair of
the 25-pair I/O connector.
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 availablepair 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 Table120 "LEI card - NT8D37 IPE module vintage level port cabling"
(page 281) for the vintage levelinformation for the NT8D37 IPE modules.
