Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector, which is described in Table B-2 and Table B-3. If you
did not order a console cable, you need to provide an RJ-45-to-DB-9 adapter cable to connect the switch
console port to a PC console port. You need to provide an RJ-45-to-DB-25 female DTE adapter if you
want to connect the switch console port to a terminal. You can order an adapter (part number
ACS-DSBUASYN=). For console port and adapter pinout information, see Table B-2 and Table B-3.
Table B-2 lists the pinouts for the console port, the RJ-45-to-DB-9 adapter cable, and the console device.
Table B-3 lists the pinouts for the switch console port, RJ-45-to-DB-25 female DTE adapter, and the
console device.
Note The RJ-45-to-DB-25 female DTE adapter is not supplied with the switch. You can order this adapter from
Cisco (part number ACS-DSBUASYN=).
