Data to be handled by SRAM(with HDD Encryption
Board

The kind of data to handle

Data to operate this machine is largely divided into 2 categories.
System software Common data among the same model
Data in SRAM and HDD Factory settings value for the target machine and the values in Address
on the boards Book and Settings/Registration, etc. entered by the user.
Upgrading and installation is used as the terms to handle the system software.
Backup and restoration is used as the terms to handle data in SRAM and HDD on the boards.
Version-up
System software
Be sure to use the latest possible backup data for the SRAM data of each board.
If restoring the SRAM data backed up long time ago, image failure, etc., may occur due to
mismatch between the backup data and the parameter for host machine adjustment changed
after backup.
■ Handling SRAM data of this machine
With the normal service, the contents of SRAM of the Main Controller PCB 2 can be backed
up to HDD in service mode and restored after replacing the board.
If there is an HDD Encryption Board, the encryption key of the HDD Encryption Board
recorded on SRAM is lost when replacing the Main Controller PCB 2, and the contents of
HDD cannot to be read. Therefore, restoration cannot be done although backup is performed.
When replacing the Main Controller PCB 2, user data needs to be reentered in the same way
as when replacing the HDD with a new one.

Main SRAM of the Main Controller PCB 2
Controller 2 includes user data and MEAP-related data.
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.
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.
Reference: If Meapback.bin is saved using
SST, it can be restored after replacing the
Main Controller PCB 2. This makes the
reinstallation of everything related to MEAP
unnecessary.
System To upgrade the system version, the Assist
installation Mode of SST is recommended.
