Figure 4-3 shows the 10/100 Ethernet ports (labeled “1” through “4”) on the CDM-625
rear panel.
1. When using the CRS-316 TMI, a PP/CAT5FF7FTGY cable (CAT5 RJ-45 to
RJ-45, 7’) is required for Ethernet management between each modem
and the CRS-512 Ethernet M&C Interface installed in the CSU rear
panel.
2. Use Port 1 only for the CRS-500 Ethernet System Communication
connection between the CRS-500 and the CDM-625 modems.
3. Avoid Ethernet Networking loops. When CDM-625s are operating in IP
Packet Processor Router or Managed Switch Mode, use only a single
port to convey traffic data for each modem.
Figure 4-3. CDM-625 10/100 Ethernet Ports
1. Use port 1 for CRS-500 to CDM-625
Ethernet System Communications.
2. Use any single port (port 2, 3, or 4)
for CDM-625 Ethernet traffic data
connection.
