REFERENCE INFORMATION
• The DEBUG port is a standard Micro-A type USB port for serial debug communications to the controller.
Note that login requires administrator level platform credentials.
• The SHT/DWN pushbutton initiates a "controlled shutdown" of the controller, ensuring that all station data is preserved.
Steps
1. Ensure that the controller's power is off.
2. Press and hold down the backup and restore button as you power up the controller, and continue holding down the button throughout the
boot-up process until the button press is detected and this confirmation banner displays:
Backup/Restore button press detected. Release button now to proceed.
3. Release the backup and restore button once the banner displays.
On detecting the button release, the system begins a 10 second countdown. The following message displays:
Press any key to restore from USB backup.
If no key pressed, factory recovery will begin in 10 seconds
Recovery begins in .... seconds
Note:
Pressing any key during this 10 second countdown prevents the system from entering factory recovery mode. Instead, the system switches
modes to restore from a USB backup.
When no key press is detected during the 10 second countdown, the factory recovery process begins at the moment the countdown finishes.
Upon entering recovery mode, the boot process overwrites the controller with a default factory image. During this process the Backup LED
blinks at slow speed (one second on, then one second off).
When the controller is in recovery mode (BACKUP LED is flashing in slow blink), do not interrupt the process. Allow the recovery to
complete. Otherwise, the controller could become inoperable.
4. When the Backup LED stops flashing, turn the controller's power off and back on again to reboot.
Note:
After restoring factory defaults the initial controller reboot process takes longer than usual. On completion, the controller is restored to a fac-
tory default state.
