1. Before Replacing
HDD can evacuate in SRAM of Main Controller PCB 2 with a service mode.
Lev1 COPIER > FUNCTION > SYSTEM > DOWNLOAD > OK[5] BACKUP
But You cannot use this function when there is HDD Encryption Board.
When there is HDD Encryption Board, like before, I back it up in the following procedures.
a) Back up contents of the SRAM by SST; and re-after board exchange; store it.
Refer to "SRAM backup method when there is HDD Encryption Board".
b) Back up contents of the SRAM by USB memory; and re-after board exchange; store it.
Refer to "Backup SRAM of Main controller 2 by USB memory".
c) Like before, You back it up in a procedure as follows.
Perform the following operations. Be sure to get an approval from the user beforehand.
1) Backup of the set/registered data

SRAM backup method when there is HDD Encryption Board
When the HDD Encryption Board is installed while the version of SST is Ver. 4.41 or later, you do not need to format the HDD or install the system even if you replace Main Controller PCB 2 as long as you can restore the SRAM image.
Procedure:
SST Ver.4.41or later, obey Steps to Upload Data; Single > Upload Data > SramImg.bin
> Save
When the HDD Encryption Board is installed:
Data in the HDD is encrypted when the HDD Encryption Board is installed.
For Main Controller PCB 2 to access to data in the HDD, the file description of the Encryption key on the HDD Encryption Board needs to be the same as that of SRAM on Main Controller PCB 2; otherwise, Main Controller PCB 2 cannot access to the data in the HDD and this causes failure in startup of the machine.
When the following parts are replaced, the procedure is as follows:
Replacement of the HDD Encryption Board
> Inconsistent description of encryption key file between Main Controller PCB 2 and SRAM on the HDD Encryption Board.
Replacement of Main Controller PCB 2
> Inconsistent description of encryption key file between Main Controller PCB 2 and SRAM on the HDD Encryption Board.
Replacement with a new HDD
> Select the following because there is no system data in the HDD: Format ALL > Download the system software
With SST Ver. 4.31 or before, it was necessary to format the HDD (Format ALL), and then install the system in any case.
With SST Ver.4.41 or later, if the description of SRAM (SramImg.bin) on Main Controller PCB 2 is kept in the PC, you can restore SramImg.bin on Main Controller PCB 2 by using SST after holding down 2 and 8 to start the machine.
When the description of SRAM on Main Controller PCB 2 can be restored, it means that the file description is the same as that of the encryption key on the HDD Encryption Board, which enables access to the HDD.
Therefore, you do not need to format the HDD or install the system when the file description of SRAM can be restored even if replacing Main Controller PCB 2.
Backup SRAM of Main controller 2 by USB memory:
Prepare for:
"USB memory storage device, which the system software for this machine is stored."
or
The USB memory recognize it in the Host machine.
On USB memory, You make the blank folder of the same name to recognize USB memory on
a service mode when You registered a system software for Host machine by SST.

2. When Replacing
1) Transferring the parts from old PCB to new PCB
DDR2-SDRAM (1 pc.) (When option DDR2-SDRAM is installed: 2 pc.)
Memory PCB
Prohibited Operation:
Do not transfer the following parts to another model (which has a different serial number).If you fail to do so, the Main Body does not activate normally and this might cause to fail the restoration.
Main Controller PCB 1
Main Controller PCB 2 (with Memory PCB installed)
Memory PCB
3. After Replacing
1) After installing the parts, turn ON the main power switch.
2) Restoring the backup data
Perform following either:
a) You download it if You upload SramImg.bin by SST.
SST Ver.4.41or later, obaey Steps to Download Data; Single > Download Data
> SramImg.bin > Start
b) Carry out Lev1 COPIER > FUNCTION > SYSTEM > DOWNLOAD > OK [8] Download Menu 2 > [2] Restore
if You carry out [5]BACKUP
c) Use the Remote UI.
Management Settings > Data Management > Import/Export
3) Resetting/registering the data
While referring to the list of set/registered data which was printed out before replacement, reset/register the data.
4) When the user generates and adds the encryption key, certificate and/or CA certificate, request the user to generate them again
