Figure: Console and AUX Port Connectors

The console port, which is an EIA/TIA-232 asynchronous serial port with an RJ-45 connector, is a

full-featured DTE connection with hardware flow control.

Connect the terminal using a thin, flat RJ-45-to-RJ-45 rollover cable and an RJ-45-to-DB-9, an

RJ-45-to-D-subminiature female, or an RJ-45-to-D-subminiature male adapter (depending on the

terminal connector).
