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).
