required specifically for HDD encryption kit
1. Initialize the encryption board via SST.
This step makes the disk unformatted (E602-0001 is triggered if the unformatted disk is
started).
2. Format the HDD and reinstall SYSTEM via SST.
When you start the HDD formatting, the message is automatically shown to confirm whether
to initialize the encryption board (Key Clear).
Key Clear will disable accesses to HDD data permanently. Cautions should be taken in Key
Clear execution.
<Points to Note in Initialization via SST>
The screen below is shown when you gain access to SST in safe mode due to E602-2000.
Poor board connection also causes this error. Check the board connection to seek error
recovery. Initialization of the encryption board will disable accesses to HDD data permanently.
Cautions should be taken in initialization.
<Points to Note in Initialization using USB>
The screen below is shown on the control panel when E602-2000 occurred and the machine
is started in safe mode using the USB flash memory with system data stored.
The message as shown in the figure below is displayed.
