Console Port Adapter Pinouts
The console port uses an 8-pin RJ-45 connector. 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=).
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=).
