Switch Module Console Port
You can connect the switch module through its console port to a PC by using the RJ-45-to-DB9 female
cable that ships with the product. If you need a spare cable, you can order a kit (part number
ACS-DSBUASYN=) directly from Cisco. If you want to attach the switch module to any other device,
such as a terminal server, you might need a different cable. For console port and adapter pinout
information, see the
