Console Port
The console port uses an 8-pin RJ-45 connector, which is described in
Table B-4
and
Table B-5
. The
supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch module to a
console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the
switch module 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-4
and
Table B-5
.
