Connecting to a Terminal
Use the supplied RJ-45-to-DB-9 adapter cable and an RJ-45-to-DB-25 female
DTE adapter to connect the console port to a terminal. Figure B-13 shows how to
connect the console port to a terminal. Table B-4 lists the pinouts for the console
port, the adapter cable, and the RJ-45-to-DB-25 adapter.
Note The RJ-45-to-DB-25 female DTE adapter is not supplied with the switch. You can
order a kit (part number ACS-DSBUASYN=) with that adapter from Cisco.
