5.7.2.2 IP (10/100 Ethernet) Interface Example (CDM-570/L ONLY)
Figure 5-32 shows the block diagram and cabling example for a CDM-570/L ONLY diversity
switching configuration using the IP (10/100 Ethernet) Interface. This configuration requires no
cabling kit – you must use user-provided Ethernet cables and hub for direct connection to the
modems.
For the CDM-570L in Managed Switch (Ethernet Bridge) Mode, you MUST use an
external Ethernet hub to insure that traffic will continue after a switchover. If an
Ethernet switch is used, there could be a several minute outage while the Ethernet
Switch “re-learns” the correct output Ethernet port. Using a “dumb” Ethernet hub
allows LAN to WAN traffic to continue even after a switchover occurs since both
modems will be receiving the LAN traffic.
