Installation
Because of the wiring in some of the system modules and cabinets, the
LEI only works in certain card slot pairs. These restrictions 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 NTAK12 Small 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.
