Auxiliary Port Signals And Pinouts - Cisco AS5300 Appendix

Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 female DTE adapter (labeled
TERMINAL) to connect the console port to a terminal. Figure D-3 shows how to connect the console
port to a terminal. Table D-1 lists the pinouts for the asynchronous serial console port, the
RJ-45-to-RJ-45 rollover cable, and the RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL).

Auxiliary Port Signals and Pinouts

Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-25 male DCE adapter (labeled MODEM)
to connect the auxiliary port to a modem. Figure D-4 shows how to connect the auxiliary port to a
modem. Table D-4 lists the pinouts for the asynchronous serial auxiliary port, the RJ-45-to-RJ-45
rollover cable, and the RJ-45-to-DB-25 male DCE adapter (labeled MODEM).
