*1: An error code is displayed when the TPM setting is "ON". Recovery
Yes SST PC
(Sramimg) procedure differs depending on the controller's version as follows:
•
Before Ver13
Perform Initialize All Data/Settings after rebooting, and then set the TPM
setting "ON" again to restore.
•
Ver.13 or later
After installation of the system, execute restoration of the TPM key to
restore.
*2: After executing each CLEAR operation, the key information in the SRAM
can be automatically restored from the common backup key in the HDD,
and the TPM setting becomes "ON". However, only the UI display is
"OFF", so it is required to change the TPM setting to "ON" manually.
*3: By initializing all data/settings, the TPM setting is changed to "OFF".
*4: Restoration is not available with other machines where the TPM setting
is set "ON".
The available range for backup of key information differs depending on
the controller's version as follows.
• Before Ver13
Backup is available only for failure with TPM PCB
• Ver.13 or later
Backup is available for effective key and settings information even in the
case of failure with HDD
