Making Signal Connections
puts. Connected routers must be situated physically next to each other, either top to bottom or side
to side.
The NV8288-Plus contains 48 expansion connections, located on the rear of the router. All 48
expansion connections must be connected to properly connect two frames together. Each signal
expansion connection corresponds to six output signals. For example, the expansion connection in
the upper, right corner corresponds to Outputs 1–6. (See Figure 2-6 on page 10.)
The signal expansion connections use a proprietary expansion cable provided by Miranda
(WC0089). The expansion connectors on the cable are colored-coded (one side black; one side sil-
ver) to ensure that they are installed correctly. The connector pins are fragile and can easily bend or
break if forced.
How to Make Signal Expansion Connections between Two Routers
1 Locate the signal expansion connections on the rear of the two router frames you are connect-
ing, as shown in Figure 3-10. The routers should be situated close together.
Figure 3-10. Expansion Connections for Connecting Two NV8288-Plus Routers
2 Facing the rear of the first router (router 1), locate the expansion connections in the upper half
of the frame.
Connect one end of the expansion connector cable (WC0089) to the expansion connection mak-
ing sure that the connector is positioned as follows. (See Figure 3-11.)
• Black side of connector faces right.
• Silver side of connector faces left.
