Console Port
The console port uses an 8-pin RJ-45 connector, which is described in
Table B-1
and
Table B-2
. The
supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the blade switch to a console
PC. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the blade 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
and
Table B-2
.
