Handling SRAM data of this machine
The following 4 methods are available to backup and restore SRAM data on the boards. See next Table to check the appropriate method for each board.
a) Data is automatically updated from the backup data in the HDD when starting the machine after replacing the board.
b) Before replacing the board, make a backup data in the HDD in service mode, and then restore the data in service mode after replacing the board.
c) Before replacing the board, save the SRAM data in the PC, and then restore the data using SST or USB memory device after replacement.
d) Before replacing the board, make a backup data in the PC from RUI, and restore the data after replacement.
Part to be replaced
Description
Procedure
When a HDD Encryption Board is installed
When TPM is enabled (ON)
Main Controller 2
The following information is stored in SRAM of Main Controller 2:
SST is used to make a backup SRAM data.
SST is used to save Sraming.bin and MeapBack.bin into a PC.
When there is no Sraming.bin while the user made a backup data from RUI, restore the data after recovery.
For MEAP-related data, explain to the user that the data needs to be reinstalled.
Backup(MeapBack.bin) is also available using SST or USB memory device.
Use SST or a USB memory device to save Sraming.bin and MeapBack.bin.
Replace Main Controller 2.
Restore Sraming.bin and MeapBack.bin that have been saved.
Hold down 2 and 8 to start the machine.
Use SST or a USB memory device to restore Sraming.bin and MeapBack.bin in Main Controller 2.
No additional work.
New HDD
Install the system software on the new HDD after formatting it by SST.
If there are any files backed up from RUI by the user, restore them after recovery.
Explain the user that the reinstallation of everything related to MEAP is necessary.
For MEAP-related data, explain to the user that the data needs to be reinstalled.
Backup(MeapBack.bin) is also available using SST or USB memory device.
Use SST or a USB memory device to save MeapBack.bin.
Use SST to format the HDD.
Hold down 2 and 8 to start the machine, and then use SST to install the system software.
Restore MeapBack.bin that have been saved.
Hold down 2 and 8 to start the machine, and then use SST or a USB memory device to clear the encryption key of the HDD Encryption Board.
Use SST or a USB memory device to install the system.
After the system is properly installed, enable TPM to execute a backup of TPM.
System installation when the HDD is properly working.
To upgrade the system version, the Assist Mode of SST is recommended.
Depending on the situation, upgrading of an individual module is available in single mode.
Enter service mode and select the following:
COPIER > FUNCTION > SYSTEM > DOWNLOAD > OK
Use SST to install the system software in Assist mode.
Hold down 2 and 8 to start the machine, and then use SST or a USB memory device to clear the encryption key of HDD Encryption Board.
Use SST or a USB memory device to install the system.
No additional work.
Backup of Reader Controller PCB
Enter service mode to make a backup of SRAM data into the HDD.
Select the following to execute system backup: COPIER > FUNCTION > SYSTEM RSRAMBUP
Replace the Reader Controller PCB
Select the following to restore the system: COPIER > FUNCTION > SYSTEM RSRAMRES
Normal operation.
No additional work.
Backup of DC Controller PCB
Enter service mode to make a backup of SRAM data into the HDD.
Select the following to execute system backup: COPIER > FUNCTION > SYSTEM DSRAMBUP
Replace the DC Controller PCB
Select the following to restore the system: COPIER > FUNCTION > SYSTEM DSRAMRES
Normal operation.
No additional work.
HDD Encryption Board
An encryption key of the HDD Encryption Board is newly made.
Install the system software on the HDD after formatting it by SST.
If there are any files backed up from RUI by the user, restore them after recovery.
Hold down 2 and 8 to start the machine, and then use SST or a USB memory device to clear the encryption key of HDD Encryption Board.
Use SST or a USB memory device to install the system.
Follow the description on the left.
After the system is properly installed, enable TPM to execute a backup of TPM.
TPM Board
When there is a backup of TPM, restore TPM.
When there is no backup of TPM, select the following: Settings/Registration > Management Settings
Restore TPM when there is a backup of TPM.
When there is no backup of TMP, use RUI to make a backup, and then select the following to restore from RUI: Settings/Registration > Management Settings > Data Management > Initialize All Data/Settings; enable TPM to make a backup.
Follow the description on the left.
Follow the description on the left.

Using SST enables the following:
SST has the following functions that are necessary for service work:
1. To download system software
2. To copy the system software into a USB memory device.
3. To backup and restore information of SRAM and MEAP in Main Controller 2.
4. To format HDD
5. To collect device log
6. To clear the encryption key of HDD Encryption Board
Upgrading using a USB memory device
Using a USB memory device, the following functions are available to upgrade the system:
1. To download system software
2. To clear download file
3. To format HDD
4. To collect device log
