RJ-45 Connector Pinouts for the Routing Engine ETHERNET Port
The port on the CIP labeled ETHERNET is an autosensing 10/100-Mbps Ethernet
RJ-45 receptacle that accepts an Ethernet cable for connecting the Routing
Engine to a management LAN (or other device that supports out-of-band
management). For more information, see “Routing Engine Management Ports”
