Identifying a Crossover Cable
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=).
