Console Port
The console port uses an 8-pin RJ-45 connector, which is described in Table B-1 and Table B-2. If you
did not order a console cable with your switch, you need to provide an RJ-45-to-DB-9 adapter cable 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-1 and Table B-2.
