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

10/100/1000 Ports

The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum
cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5,
Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use
Category 3 or Category 4 UTP cable.
For more information about the 10/100/1000 Ethernet port connections and specifications, see the
