USB Type A Port
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 Configuration Guide, Cisco IOS Release 15.2(5)EX (Cisco Catalyst
Digital Building Switches).
USB Type A Port
The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB
keys) and to USB Bluetooth devices.
The port supports 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). 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.
The port supports USB Bluetooth devices. The USB Bluetooth device acts as a Bluetooth host and serves as
either a serial port or a management port connection. You can pair it with your Bluetooth smart phone, laptop,
or tablet.
SD Flash Memory Card Slot
The switch supports a Secure Digital(SD) flash memory card that makes it possible to replace a failed switch
without reconfiguring the new switch. A cover protects the flash card and holds the card firmly in place. The
cover is hinged and closed with a captive screw. This prevents the card from becoming loose and protects
against shock and vibration.
Up to 2GB of Cisco SD memory card is supported.
LEDs
You can use the switch system and port LEDs to monitor switch activity and performance. The LEDs remain
off by default when switch is powered on. Press the Mode button to turn on the LEDs.
