10 IFC Networking—Serial Interface Board (SIB-NET)
The ICA-4L chassis includes an extra pin (16th) when connected to an
older power cable (Part Number 71030). When the power cable is
connected to the pin connector on the top of the ICA-4L chassis (in the
first tier), the extra pin is in front, facing the door of the cabinet (Figure 2).
The extra pin is not engaged in the power cable’s plug and is therefore
exposed. The power cable Part Number 75378 has 16 positions, which will
connect properly with the ICA-4L. If the newer cable 75378 is used with
the older ICA-4 chassis, there will be an extra 16th socket position on the
cable. This empty cable socket should be located to the front of the ICA-4
pin header.

Note: Expansion power cable (Part Number 75142) remains at 15 positions.
There is an extra receptacle on the ICA-4L chassis bottom connector when
connecting an ICA-4 to the bottom of an ICA-4L. This receptacle should
also be in the front. Connecting two ICA-4Ls does not produce extra pins
or receptacles. For connection of two ICA-4L chassis, which are
physically mounted in non-adjacent tiers of the CAB enclosure, use an
expansion power cable (75142) and see Figure 3.
When connecting two ICA-4L chassis using an expansion power cable
(75142), there will be an extra pin on one chassis and an extra receptacle
on the other. Both the extra pin and the receptacle should be in the front,
facing the cabinet door (Figure 3).
