B.3.2.4 CRS-520 TMI – 10/100 Ethernet Connectors (RJ-45F)
The CRS-520 TMI provides four standard RJ-45F User Interface ports, operating at 10/100 Mbps,
half and full duplex, auto-negotiating for Ethernet Router Modes.
Table B-7
indicates the typical pinout for each of these connectors (10/100 Ethernet User “Port 1”
through “Port 4”).
User Port 1 is reserved for use as the CRS-500 Ethernet System Communication
connection between the CRS-500 and the modems.
To avoid Ethernet Networking loops, CDM-625/As operating in IP Packet
Processor Router Mode use only a single port of the CDM-625/A’s remaining
available ports (i.e., “Port 2” OR “Port 3” OR “Port 4”) to convey traffic data for
each modem at any given time.
