Figure 2-10 Identifying a Roll-Over Cable
The Cisco 7200 series routers ships with a rolled cable. Connection to a terminal or a modem will require
an RJ-45-to-DB-25 adapter, and possibly a DB-25-to-DB9 adapter. Refer to Table 2-3 for the cable and
adapter configurations that can be used to connect terminals and modems to the Cisco 7200 series
routers.
Both ports are configured as asynchronous serial ports. Figure 2-11 shows the RJ-45 console and
auxiliary port connections.
For console and auxiliary port pinouts for the RJ-45 connector, see Appendix A, “Specifications,” the
uckers3cat.
