closed for the router cooling system to work properly.
Making Signal Connections
In order for the NV8288 or the NV8288-Plus to properly manage incoming and outgoing signals,
the I/O connections on the rear of the router must be connected to cables that receive and distribute
the signals. The NV8288 contains up to 288 input connections and up to 576 output connections.
The NV8288-Plus in standalone mode contains up to 288 input and 288 output connections.
If connecting two NV8288-Plus routers together, additional signal expansion connections must also
be connected. These connections enable each router to both send and receive signals between the
routers. (See
Signal Expansion Connections on page 35.)
Local Signal Connections
Cables are connected to the I/O connections using DIN 1.0/2.3 connectors and Belden 1855A
cable, or an equivalent. For installation, it is recommended that you use a connector tool designed
for tightly spaced connectors.
