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
“Connector and Cable Specifications” section on page B-1.
Ports 19 to 22 10-Gigabit Ethernet module slots for use with the Cisco TwinGig Converter
Modules and Cisco X2 transceiver modules.
Ports 23 to 26 External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that
support auto-MDIX and autonegotiation.
Internal 100BASE-T
Ethernet port
The Ethernet management port (Fa0) is used only for switch module
management traffic, not for data traffic. It is connected to the
Onboard
Administrator through the blade enclosure backplane connector.
Traffic
to and from this port is isolated from the switch ports. This port only
supports autonegotiation with 100 Mb/s and full-duplex mode.
StackWise Plus ports Stacking cable ports.
Console port Switch module management port (RJ-45 connector).
