5.12 Cabling the CDM-600L (CLM-9600L)

1) For information on configuring the CRS-170A L-Band 1:1 Redundancy Switch with the
CDM-600L (CLM-9600L) Open Network Satellite Modems for 1:1 operation, see:
• Chapter 4. MODEM
• CLM-9600L Open Network Satellite Modem Installation and Operation Manual (CEFD
P/N MN/CLM9600L.IOM)
• CRS-150 1:1 Redundancy Switch Installation and Operation Manual
(CEFD P/N MN/CRS150.IOM)
2) For information on the cables and cable assemblies specified in this section, see
Appendix A. CABLE DRAWINGS.
Figure 5-64 shows the block diagram for connecting a pair of CDM-600L (CLM-9600L) Open Network
Satellite Modems together with the CRS-150 and CRS-170A switches. This figure also provides a table that
identifies the cable assemblies that may be supplied with the CRS-170A in this configuration.
When you connect the Control Interface cables between the CRS-170A, the CRS-150, 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.
