Module Slots and Rear Connections
Rear Connections
The rear of the NV8256-Plus (Figure 2-4 on page 10) features a backplate containing BNC connec-
tions: 256 for receiving signals and 256 for distributing signals. These connections are passive and
pass the signals through to active, receiving connections on the input cards and output cards.
An additional set of four BNC connections, located in the upper, center area of the frame, send sig-
nals to the monitor card. In the lower region of the frame are connections for system and power
functions, as shown in Figure 2-5 on page 11. In the center of the frame are connections for expan-
sion cables used to send signals between two connected NV8256-Plus router frames. In Figure 2-4
on page 10, the expansion connections are shown with the cover plates still on.
