Use the thin, ﬂat, RJ-45-to-RJ-45 roll-over cable and RJ-45-to-DB-25 female DTE adapter

(labeled “TERMINAL”) to connect the console port to a terminal. Figure C-3 shows how

to connect the console port to a terminal. Table C-2 lists the pinouts for the asynchronous

serial console port, the RJ-45-to-RJ-45 roll-over cable, and the RJ-45-to-DB-25 female

DTE adapter (labeled “TERMINAL”).
