Installing and Connecting the Router
Auxiliary Port, Console Port, and Adapter Pinouts for the Cisco CGR 2010 Router
Auxiliary and Console Ports
The console and auxiliary ports on Cisco IOS® routers are asynchronous serial ports. The console port and the auxiliary
port are configured as data terminal equipment (DTE). For Cisco 2000 Series Routers, the console and auxiliary ports
both use RJ-45 connectors. Adapters are available for connections to PC terminals, modems, or other external
communications equipment.
Table 4 on page 46 shows the console port pinouts for the RJ-45 connector. Any pin not referenced is not connected.
Table 5 on page 46 shows the auxiliary port pinouts for the RJ-45 connector. Any pin not referenced is not connected.
Identify a Rollover Cable
To identify a rollover cable, compare the two modular ends of the cable ( Figure 16 on page 47 ). Hold the cables in your
hand, side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left connector (pin 1)
must be the same color as the pin on the outside of the right connector (pin 8).
On Cisco cables, pin 1 is white on one connector, and pin 8 is white on the other connector.
