HDD-related Message
When an error occurs to the HDD, the HDD abnormality message appears on the operation panel and
the screen for formatting is displayed. Also when replacing the HDD, a message "Hard Disk is
replaced." appears on the operation panel and the screen for formatting is displayed.
Refer to the table shown below for the conditions of the message display.
Even when replacing the controller board, a banner "Hard Disk is replaced." appears. It is because the
machine recognizes HDD has been replaced when the controller board that does not hold the HDD
identification information is attached.
