Signal Flow and Signal Numbering
Port Ordering in Frame 2
Both input and output ports in frame 2 start at 577 and end at 1152. Thus the card in slot 1 of
frame 2 has port space 577–585.
However, I/O port numbers depend on a different slot ordering. This is the ordering of slots for
input port numbering, as viewed from the rear:
Fig. 6-3: NV8576-Plus Slot Order for Input Port Numbering
This is the ordering of slots for output port numbering:

Here too, cards and backplanes in the lower bays are installed “upside down,” that is rotated
180° with respect to the cards and backplanes in the upper bays.
