Making Signal Connections
In order for the NV7512 to properly route incoming and outgoing signals, the I/O connections on
the rear of the router must be connected to cables that receive and distribute the signals. The
NV7512 contains a maximum of 512 input connections and a maximum of 512 output connections.
The total number of connections depends on the type of signals being routed and the corresponding
backplane installed. (See
Backplanes on page 12.)
If connecting two or more NV7512 routers together, additional signal expansion connections must
also be connected. These connections enable the routers to send and receive signals between the
connected routers. (See
Signal Expansion Connections on page 53.)
