connected, turn power to the BreadCrumb OFF and then ON again. Observe the Status LED to

monitor progress. If, during this second firmware upgrade attempt, another error occurs, take

note of the new error code and then apply for technical support.

4. When complete, turn power to the BreadCrumb OFF, disconnect the USB storage device, then turn

power to the BreadCrumb back ON.

5.2 Zeroize

CAUTION

Do NOT turn off or reboot a BreadCrumb while it is being zeroized. An interruption to power during the

zeroization process can result in the BreadCrumb being unable to boot properly.

5.2.1 Over the Air Zeroize

If it is necessary to erase all settings of a BreadCrumb, the BC|Commander Zeroize feature can be used.

This feature is found in the BreadCrumb menu and in the right mouse contextual menu of a selected

BreadCrumb. This is an over-the-mesh-network operation, whether wired or wireless. Note that a Zeroize

(or Config Reset) will likely make that BreadCrumb unable to connect to your mesh due to incompatible

settings so it is best to use this feature only on BreadCrumbs that can be physically accessed.

With firmware version 11.17.7 and higher, the BC|Commander Zeroize dialog will offer a choice or a full

Zeroize or a Config Reset that retains logs.

An Over the Air Zeroize (or Config Reset) will automatically reboot the BreadCrumb when it completes.

Important: Regarding Physical Access

Physical access to the device will likely be required for re-configuration.

5.2.2 USB-Based Zeroize

Version 11 firmware includes 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 Bread-

Crumb’s location and requires a properly prepared USB storage device. To perform the zeroize process,

follow these procedures:

1. Prepare a USB storage device using BC|Commander by selecting the “Zeroize (Do Not Upgrade)” op-

tion in the USB Flash Manager. Please see the BC|Commander Version 11 User Guide (Administrative

Tasks – USB-Based Zeroize) for more detailed instructions on how to properly prepare the USB stor-

age device.

2. Connect the USB storage device to the BreadCrumb’s USB port (and if the BreadCrumb is powered

off, turn on the BreadCrumb at this time).

Note

With version 11, 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.
