The management ports
connect the switch to a PC running Microsoft Windows or to a terminal server.
Ethernet management port.
RJ-45 console port
USB mini-Type B console port
Ethernet management port connection uses a standard RJ-45 crossover or
straight-through cable. The RJ-45 console port connection uses the supplied
RJ-45-to-DB-9 female cable. The USB console port connection uses a USB Type A
to 5-pin mini-Type B cable. The USB console interface speeds are the same as
the RJ-45 console interface speeds.
If you use the USB mini-Type
B console port, the Cisco Windows USB device driver must be installed on any PC
connected to the console port (for operation with Microsoft Windows). Mac OS X
or Linux do not require special drivers.
The 4-pin mini-Type B
connector resembles the 5-pin mini-Type B connectors. They are not compatible.
Use only the 5-pin mini-Type B.
Figure 3. USB Mini-Type B Port. This illustration
shows a 5-pin mini-Type B USB port.
With the Cisco Windows USB
device driver, you can connect and disconnect the USB cable from the console
port without affecting Windows HyperTerminal operations.
The console output always
goes to both the RJ-45 and the USB console connectors, but the console input is
active on only one of the console connectors at any one time. The USB console
takes precedence over the RJ-45 console. When a cable is connected into the USB
console port, the RJ-45 console port becomes inactive. Conversely, when the USB
cable is disconnected from the USB console port, the RJ-45 port becomes active.
You can use the command-line
interface (CLI) to configure an inactivity timeout which reactivates the RJ-45
console if the USB console has been activated and no input activity has
occurred on the USB console for a specified time.
After the USB console
deactivates due to inactivity, you cannot use the CLI to reactivate it.
Disconnect and reconnect the USB cable to reactivate the USB console. For
information on using the CLI to configure the USB console interface, see the
