RJ-45 Connector Pinouts for the Routing Engine ETHERNET Port

The port on the CIP labeled ETHERNET is an autosensing10/100-Mbps Ethernet
RJ-45 receptacle that acceptsan Ethernet cable for connecting the Routing
Engine to a management LAN (or other device thatsupports out-of-band
management). For more information, see “Routing Engine Management Ports”
on page 33. Table 28 describes the RJ-45 connector pinout.
