Overview of the Routers
Figure 1-5 shows the rear of the NV8144. The farthest left-hand section is a blank plate that
corresponds in position to the control cards. Next to the control card plate are 16 input back-
plane slots. A mixture of different input cards and their backplane modules can be placed in
these slots.
The middle section contains system connections for audio reference, video reference, control
system connections, and power supply alarms.
To the right of the system connectors is one monitor backplane slot.
To the right of the monitor backplane are 8 output backplane slots. A mixture of different
output cards and their backplane modules can be placed in these slots.
At the very top of the frame is a grill for exhausting warm air dispersed by the fans. (See Frame
Cooling on page 6.) Near the bottom of the frame are two AC power connectors. To the right of
the left-hand power connection is a power supply alarm connector. (See Alarms on page 109.)
