• Always use shielded USB cables with a properly terminated shield. The USB serial console interface
cable must not exceed 3 meters in length.
• Only one console port can be active at a time. When a cable is plugged into the USB console port, the
RJ-45 port becomes inactive. Conversely, when the USB cable is removed from the USB port, the RJ-45
port becomes active.
• 4-pin mini USB Type-B connectors are easily confused with 5-pin mini USB Type-B connectors. Note
that only the 5-pin mini USB Type-B is supported
Note
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit.
For operation with a Microsoft Windows OS version older than Windows 7, the Cisco Windows USB Console
Driver must be installed on any PC connected to the console port. If the driver is not installed, the prompts
guide you through a simple installation process.
The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the console
port without affecting Windows HyperTerminal operations. No special drivers are needed for Mac OS X or
Linux.
Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.
