Making Signal Connections
2 Locate the expansion connections labeled ‘XPT 1’ on each router frame being connected.
First, connect to the signal expansion connections on each frame, looping serially from one
frame to the next, as shown in Figure 2-16. Connect each ‘OUT’ expansion connector to the
corresponding ‘IN’ connector on the next router. Similarly, connect each ‘IN’ expansion con-
nector to the corresponding ‘OUT’ connector on the next router. For example, on
Router 1, ‘OUT 1’ is connected to ‘IN 1’ on Router 2. For another example, see Figure 2-18 on
page 57.

First Set of Connections
Next, connect to the signal expansion connections on each frame, looping serially from one
frame to the next, as shown in Figure 2-17.

Second Set of Connections
Use the following table as a reference when making signal expansion connections. Each set of
‘IN’ and ‘OUT’ connections are divided into sets that correspond to a crosspoint card: ‘XPT 1’,
‘XPT 2’, ‘XPT 3’ and ‘XPT 4’. The ‘IN’ and ‘OUT’ numbers correspond to the numbers listed
next to each signal expansion connector. (See Figure 2-18 on page 57.)
The following table lists each connection by whether it is an ‘IN’ or ‘OUT’ connection, then the
crosspoint card number (1, 2, 3 or 4) and lastly the ‘IN’ or ‘OUT’ number (1, 2 or 3). For exam-
ple, in the Router 1 column, ‘IN 2-1’ represents the connector in the ‘XPT 1’ section labeled
‘IN 2’. Similarly, ‘OUT 4-1’ represents the connector labeled ‘OUT 1’ in the ‘XPT 4’ section.
