USB Mini-Type B Console Port

The switch has the following console ports:
• USB mini-Type B console connection
• RJ-45 console port
Console output appears on devices connected to both ports, but console input is active on only one port at a
time. By default, the USB connector takes precedence over the RJ-45 connector.
Windows PCs require a driver for the USB port. See the hardware installation guide for driver installation
Note
instructions.
Use the supplied USB Type A-to-USB mini-Type B cable to connect a PC or other device to the switch. The
connected device must include a terminal emulation application. When the switch detects a valid USB
connection to a powered-on device that supports host functionality (such as a PC), input from the RJ-45
console is immediately disabled, and input from the USB console is enabled. Removing the USB connection
immediately reenables input from the RJ-45 console connection. An LED on the switch shows which console
connection is in use.
Console Port Change Logs
At software startup, a log shows whether the USB or the RJ-45 console is active. Each switch in a stack issues
this log. Every switch always first displays the RJ-45 media type.
In the sample output, Switch 1 has a connected USB console cable. Because the bootloader did not change
to the USB console, the first log from Switch 1 shows the RJ-45 console. A short time later, the console
changes and the USB console log appears. Switch 2 and Switch 3 have connected RJ-45 console cables.

changes to the RJ-45 console interface:

You can configure the console type to always be RJ-45, and you can configure an inactivity timeout for the
USB connector.
USB Type A Ports
The USB Type A ports provide access to external USB flash devices, also known as thumb drives or USB
keys. The switch supports Cisco 64 MB, 256 MB, 512 MB, 1 GB, 4 GB, and 8 GB flash drives. You can use
standard Cisco IOS command- line interface (CLI) commands to read, write, erase, and copy to or from the
flash device. You can also configure the switch to boot from the USB flash drive.
