Configured State Alternate State

On Off

Off N/A

Alerts Only On

Off (switchable) On

Note that state changes can occur only between options in the same rows of the table above. For exam-

ple, it is possible to toggle the state back and forth between Alerts Only and On, but not between Alerts

Only and Off. Transitioning from Alerts Only to Off would require changing the LED mode setting in

BC|Commander.

The default LED Mode for the BreadCrumb ES1 is On.

Note

There are two different configurable Off states: Off (switchable), which toggles to On, and Off (non-

switchable), which has no alternate state. If the LED Mode is set to Off (non-switchable), the Configura-

tion Switch will NOT turn it on.

2.7.2 Zeroize Keys and Restore Factory Defaults (Reset)

Note

The BreadCrumb Zeroize aka Reset switch defaults to a quicker “Reset Config” that clears all configura-

tion but retains logs. The type of Zeroize operation performed by the button is controlled by a configu-

ration setting in the BreadCrumb (in General… Physical Buttons).

This mode is used to erase the security protocol keys of a BreadCrumb and to restore its software config-

uration to the factory default state. To operate this switch follow these procedures:

• Ensure that the BreadCrumb is powered on, has fully booted-up and its Status LED color is green or

blue.

• Press and hold the switch until the Status LED changes to blinking yellow (approximately 10 se-

conds), then release the switch.

• On a full Zeroize operation, the Status LED will flash the yellow warning code “321” (BreadCrumb is

being zeroized) then flash rapidly yellow. This indicates that the Zeroize Keys and Restore Factory

Defaults operation has been initiated and is in progress.

• On a full Zeroize operation, the Status LED should flash the red error code “32” (BreadCrumb has

been zeroized). This error code will flash for up to 30 seconds.

• The BreadCrumb will then automatically reboot using the factory default configuration.

See Appendix Error and Warning Codes for a description of blinking LED numeric codes.

Warning

Do NOT turn off or reboot a BreadCrumb that is being zeroized. An interruption to power during the ze-

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

Tip

The process of zeroizing keys and restoring factory defaults can also be performed remotely with the

BC|Commander management software or with a properly prepared USB drive. For more information,

refer to the

BC|Commander Version 11 User Guide

.

For a list of error and warning codes refer to Appendix Error and Warning Codes.
