The console port uses an 8-pin RJ-45 connector, described in
Table B-2. The supplied RJ-45-to-RJ-45 rollover cable and DB-9 adapter are used
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
This section describes the cables and adapters used with Catalyst 3550 switches.
The schematics of crossover and straight-through cables are shown in
