Front Module Slots and Rear Connections
Rear Connections
The rear of the NV8500 family router frames (Figure 1-21 on page 28) feature a back plate contain-
ing openings for installing interchangeable backplanes housing connectors. The type and number of
connectors change depending on the signal being managed and which of the NV8500 family rout-
ers are being used.
NV8144
The rear of the NV8144 houses backplanes and system connections. When facing the rear, the far-
thest left-hand section has a blank plate. This corresponds to the control cards, which are installed
through the front of the router frame. Next to the control card plate are 16 backplanes housing con-
nectors for receiving incoming signals. These backplanes are installed in slots that correspond to
active cards for inputs. (See Front Slots
on page 20.) The middle section contains system connec-
tions, such as audio and video references, control systems, and so on. For details, see System Con-
nections on page 32.
To the right of the section containing the system connections is a single backplane for monitor sig-
nals. To the right of the monitor backplane are 8 backplanes housing connectors for distributing
outgoing signals. These backplanes are installed in slots that correspond to active cards for outputs.
At the very top of the frame are grills for exhausting warm air dispersed by the fans in the fan tray.
Near the bottom of the frame are two power connections for connecting the two power supply mod-
ules to power. To the right of the left-most power connection is a connection for alarms. For details,
see System Alarm
on page 36.
