5.3 USB-Based Zerioze
As of firmware version 10.27, there is a USB-based Zeroize feature. This feature does not upgrade or in
any other way affect the firmware version running on the BreadCrumb. This process takes place at the
BreadCrumb's location and requires a properly prepared USB storage device. To perform the firmware
upgrade process, follow these procedures:
1. Prepare a USB storage device using BC|Commander by selceting the “Zeroize (Do Not
Upgrade)” option in the USB Flash Manager. Please see the BC|Commander v11 User Guide
(Administrative Tasks – USB-Based Zeroize) for more detailed instructions on how to properly
prepare the USB storage device.
2. Connect the USB storage device to the BreadCrumb's USB port and turn on the BreadCrumb.
Note
With v11, the USB drive can be connected to a live BreadCrumb and the zeroize process
will begin automatically.
3. The USB-based Zeroize process will take less than a minute. Observe the BreadCrumb's Status
LED to monitor progress. Wait for the LED to flash error code 32 “BreadCrumb has been
zeroized.”
4. Turn power to the BreadCrumb OFF, disconnect the USB storage device, then turn power to the
BreadCrumb back ON.
