How to Make Input Monitor Connections
Because NV8144 only uses one monitor card and backplane, this procedure does not apply to that
router. This procedure applies to the NV8280/NV8280-Plus and NV8576/NV8576-Plus routers.
1 Locate the input monitor backplanes as described in step 1 of the previous procedure.
2 For each connection, use a DIN 1.0/2.3 connector and 1855A Belden cable, or an equivalent
(provided with product package), and make connections as follows:
NV8280/NV8280-Plus
— connect ‘OUT 1’ and ‘OUT 2’ on the input monitor backplane to
your monitoring equipment.
For NV8576/NV8576-Plus:
a Connect ‘OUT 1’ of the input monitor backplane in the lower bay, to ‘IN 1’ of the input
monitor backplane in the upper bay, as shown in Figure 2-24
b Similarly connect ‘OUT 2’ of the input monitor backplane in the lower bay, to ‘IN 2’ of the
input monitor backplane in the upper bay, as shown in Figure 2-24.
c Connect ‘OUT 1’ and ‘OUT 2’ of the input monitor backplane in the upper bay to your
monitoring equipment, as shown in Figure 2-24:
Expansion Frame Monitor Connections
If you have connected two expandable router frames (NV8280-Plus or NV8576-Plus), only one
router is connected directly to the monitoring equipment. This is the primary router. Monitor
expansion connections are then made between the primary router and the other, or secondary,
router. This enables the monitoring equipment to sample all signals on both routers through the
monitor connections on the primary router.
How to Make Output Expansion Monitor Connections for NV8280-Plus
1 Connect ‘OUT 1’ of the output monitor backplane in the secondary frame to ‘IN 1’ of the out-
put monitor backplane of the primary frame, as shown in Figure 2-25.
2 Connect ‘OUT 2’ of the output monitor backplane in the secondary frame to ‘IN 2’ of the out-
put monitor backplane of the primary frame, as shown in Figure 2-25.
Note Unused ‘IN’ connectors are not to be terminated.
