8. NV8576 I/O Signal Numbering
Signals are received and distributed through I/O cards and connectors housed on a backplane. Each
signal is assigned a number that corresponds to the physical input or output connector and to the
slot in which an input card or output card is installed. The following illustrations list the signal
numbers assigned to I/O connections on the NV8576 and NV8576-Plus frames. For more informa-
tion on signal numbering, and for numbering on the NV8280, NV8280-Plus and NV8144 frames,
