Console and Auxiliary Port Signals and Pinouts

The console port is conﬁgured as data communications equipment (DCE), and the auxiliary

port is conﬁgured as data terminal equipment (DTE). The console and auxiliary ports both

use RJ-45 connectors. RJ-45-to-DB-25 adapters are available for connection to modems

and other external communications equipment. Both ports are conﬁgured as asynchronous

serial ports.

Following are the pinouts for the console port (see Table C-1), the auxiliary port (see

Table C-2), and the adapter (see Table C-16 and Table C-17).
