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.

Identify a Rollover Cable
To identify a rollover cable, compare the two modular ends of the cable
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.
