Unit-to-Switch IF Interface Connection

Excluding the CDM-840s, the KT-0000160 CRS-170A L-Band 1:1 Redundancy Kit (Section
5.2.1) provides all components shown in Figure 5-29.
IMPORTANT: The Tx IF from 'Unit A' connects to the Tx IF port 'J5 | Tx A' on the CRS-170A;
similarly, the Tx IF from 'Unit B' connects to the Tx IF port 'J6 | Tx B' on the CRS-170A. The
same logic applies for the Rx IF connections. It is important to note that failure to observe
this requirement will result in system malfunction.
