Console Port Adapter Pinouts

The RS-232 console port uses an 8-pin RJ-45 connector. Use an RJ-45-to-DB-9 adapter cable to connect the
switch console port to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter to connect
the switch console port to a terminal. You can order the kit (part number ACS-DSBUASYN=) from Cisco.
