Console Port
The console port uses an 8-pin RJ-45 connector, which is described in Table B-4 and Table B-5 . The
supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC.
You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console
port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from
Cisco. For console port and adapter pinout information, see
Table B-4 and Table B-5 .
