Clearing the NVRAM
When replacing the controller board for a model in which the HDD encryption unit has been installed and
a customer has lost the encryption key, clearing the NVRAM is required to recover the HDD encryption
unit.
1. Prepare an SD card which is initialized.
2. Make the "restore_key" folder in the SD card.
3. Make an "nvram_key.txt" file in the "restore_key" folder in the SD card.
4. Input "nvclear" into the "nvram_key.txt" file.
5. Turn on the main power switch.
6. Confirm that the prompt on the LCD tells you to install the SD card (storing the encryption key) in the
machine.
7. Turn off the main power switch.
8. Insert the SD card that contains "nvclear" into slot 1.
9. Turn on the main power switch, and the machine automatically restores the encryption key in the flash
memory on the controller board.
10. Turn off the main power switch after the machine has returned to normal status.
11. Remove the SD card from slot 1.
12. Turn on the main power switch.
13. Initialize the NVRAM (SP5801-001) and HDD unit (SP5832-001) with SP mode.
14. The user must enable the HDD encryption unit with a user tool.
