Figure 1-9 shows the rear of the NV8280. At the very top of the frame is a grill for exhausting
warm air dispersed by the fans. Directly below the fan tray, starting from the left, are 2 monitor
backplane slots. To the right of the monitor backplane slots are 32 output backplane slots. A
mixture of different output cards and their backplane modules can be placed in these slots.
Directly below the output slots, starting from the left, is a blank back plate that corresponds in
position to the control cards. Next to the blank back plate are 32 input backplane slots. A
mixture of different input cards and their backplane modules can be placed in these slots.
At the very bottom of the frame, on the left-hand side, are system connections for audio refer-
ence and video reference, control system connectors, and alarm connectors. On the right-hand
side is a single power connector that connects the router to an NV8300 power supply frame. For
