The console port uses an 8-pin RJ-45 connector, which is described in
and
Table
B-2. The supplied RJ-45-to-DB-9 adapter cable is 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-2.
These sections describe the cables and adapters used with Catalyst 3750 switches.
