This is the ordering of slots for output port numbering:
Fig. 2-8: NV8576-Plus Slot Order for Output Port Numbering
The video port ordering is the same for frame 2 of an expanded NV8576-Plus, but the video port
numbering ranges from 577 to 1152 instead of from 1 to 576.
I/O Backplanes
Signals are received and distributed through backplanes installed in the rear of the router frame.
For proper operation, each backplane must match its corresponding input card or output card.
That means a coax backplane must match a coax I/O card and a fiber optic backplane must
match a fiber optic I/O card.
However, a coax input backplane can match a standard input card (video or AES), a disem-
bedder card, or a 3Gig/TDM (MADI) card, as long as the card is also designated “coax.”
Standard and hybrid I/O cards can use the same backplanes for similar signals.
Fiber optic cards and backplanes are not used for hybrid I/O.
See Chapter 5, Monitoring on page 89 for information about monitor cards and their
backplanes.
