Figure 2-1 shows the hybrid port assignments of the coax I/O backplanes:
Fig. 2-1: I/O Backplane Modules As Used for Hybrid I/O
The fiber and WECO backplanes have the same port numbering method as the coax backplanes.
Note that the coax backplanes used for hybrid cards are also used for standard cards. If, for
example, you exchange a standard card for a hybrid card in a particular slot, it is not necessary to
change the backplane, as long as the card is a coax-compatible card.
The video ports of frame sync input backplane modules follow the same pattern as for the
disembedder backplane modules.
The NV8140 is the only router in the NV8500 family that uses 18-connector disembedder (input)
backplanes and 18-connector MADI (3Gig/TDM) input backplanes. (Frame sync input back-
planes are not available for the NV8140.)
See Backplanes Having SFP Modules on page 42 for IP gateway signal numbering and ordering.
See M3 Cards on page 185 for M3 signal numbering and ordering.
