Cabling to the Advanced VSAT CDM-850

1) For information on the CDM-850's 1:1 auto-enable functionality, see:
• Chapter 4. MODEM AND SWITCH CONFIGURATION
• CDM-850 Remote Router Installation and Operation Manual
(CEFD Part No. MN-CDM850)
2) For information on the cables and cable assemblies specified in this section, see
Appendix A. CABLE DRAWINGS.
5.5.1 CRS-170A  CDM-850 Control and IF Interface Connections Using
Cabling Kit KT-0000160
The CDM-850 employs 10/100/1000 Ethernet (Gigabit Ethernet, also identified throughout
this chapter as GigE or GbE) as its sole terrestrial data interface. All cables and switches
must be user-supplied. See Section 5.5.2 for the CDM-850 Gigabit Ethernet terrestrial data
interface configuration and connection examples and details.
You must use Comtech EF Data's KT-0000160 1:1 Redundancy Control/IF Interface Cabling Kit (Section
5.2.1) for your control and L-Band Unit-to-Switch cabling connections. Figure 5-23 and Figure 5-24 show
how to connect a pair of CDM-850s together with the CRS-170A L-Band 1:1 Redundancy Switch module.
The table included with each figure lists the items you will need from this kit for your initial setup.
IMPORTANT: It is ESSENTIAL that you make the Control and the IF Rx and Tx connections
correctly. See Section 5.5.1.1 for details about the CDM-850 Unit-to-Switch Control
Interface connection, and Section 5.5.1.2 for details about the CDM-850 Unit-to-Switch IF
Interface connections.
