CRS-180 70/140 MHz IF 1:1 Redundancy Switch
Cables and Connections
CAUTION – It is ESSENTIAL that you make the control and the IF Rx and Tx
connections correctly.
5.4.1.1
Switch-to-Modem Control Interface Connection
1) Excluding the modems, the KT/11599 1:1 Redundancy Control/IF Interface
Cabling Kit (see Sect.5.4.1) provides all components shown in Figure 5-22.
2) When you connect the Control Interface cables between the CRS-180 and the
modems, make sure that you securely fasten the screw locks on the Type 'D'
connectors. This prevents accidental disconnection of the cables, particularly
when you are removing and replacing a standby unit.
