Introduction
Overview of the Routers
Figure 1-7 shows the rear of the NV8140. The farthest left-hand section is a blank plate that
corresponds in position to the control cards. Next to the control card plate are 8 input backplane
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 monitor backplane are 16 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.)
Fig. 1-7: NV8140 (Rear View)
The NV8140 uses PS8300 power supplies, not PS8100s. It has two C19 power connectors and
require 20A plant lines. The cable supplied in North America has a NEMA L5-20P connector at
the other end. For customers outside North America, we ship these power cords with the NEMA
end cut off.
The input backplane modules of the NV8140 have 18 connectors, not 9 as for the other routers.
