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 software guide.

USB Type A Port

The USB Type A port provides access to external USB flash devices (also known as thumb

drives or USB keys).

The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB (USB

devices with port densities of 128 MB, 256 MB, 1 GB, 4 GB, and 8 GB are supported).

When combined with stacking, you can upgrade other switches in the stack from an USB

key inserted in any switch within the stack. Cisco IOS software provides standard file

system access to the flash device: read, write, erase, and copy, as well as the ability to

format the flash device with a FAT file system.

SFP and SFP+ Module Slots

The switch has either two or four 1-Gigabit SFP or two 10-Gigabit SFP+ module slots. The

slots marked SFP+support both SFP and SFP+ modules. The SFP slots support only the

SFP modules.
