• Defective CPU
• Defective bus (Because of equal-length
wiring, even if one of the cables is defective,
a device connected to that bus becomes
unstable.)
*In a case of a failure in the line from the
CPU to the SDRAM CS, operation of the
LEDs is irregular.

Writing of updater-file data to the flash
memories of the drive unit (SOUTH CPU/
Servo 1/Servo 2) is in progress.
*Currently, the Firmware Updating Program
(DJS) method is not supported.
(During updating)
Communication with the control unit
(NORTH Unit) is not possible.
Servo drive 1
ATAPI 1 communication is not possible with
the drive 1 optical disc controller.
Memo: If several devices are in failure, the least critical failure is indicated with the LEDs.
Memo: If the S5 step is successfully cleared, the startup sequence will not be interrupted even if not all devices
operate properly.
Memo: It may take dozens of seconds for the unit to determine OK or NG for devices other than the AUDIO
DSP/FPGA, because of retries.
