5.4.2 Unit-to-User Data Interface Connections and Examples
In addition to the control and IF Unit-to-Switch cabling shown previously, the CDM-850 features
an eight-port 10/100/1000 Gigabit Ethernet data interface.
5.4.2.1 CDM-850 Managed Switch (Ethernet Bridge) Mode
Figure 5-20 shows the block diagram for a CDM-850 1:1 redundant configuration in Managed
Switch (Ethernet Bridge) Mode. Figure 5-21 shows the cabling example for this setup. This
configuration requires no cabling kit – you must use user-provided Ethernet cables and Layer 2
switches for direct connection to the modem via one to eight RJ-45 ports. Both figures depict all
eight ports used.
