2.2 Diagnosis

The MO drive has an initial self-diagnosis function, which checks the normal basic operation of the MO drive.

•Initial self-diagnosis function

When the power is turned on, the MO drive executes initial self-diagnosis, which includes a basic test of hardware functions.

If an error is detected during self-diagnosis, the LED on the front panel of the MO drive blinks. The status can be cleared by turning the power off and then on again. When this status is cleared, the MO drive re-executes the initial self-diagnosis.

2.3Troubleshooting Method

The system-level troubleshooting steps listed below are performed for determining if the fault is caused by an MO drive unit or caused by a system. The steps should be performed by customers on-site.

Item	Recommended procedure
MO cartridge	Check that a recommended MO cartridge is loaded and the surface
	of the disk is free from dirt or scratches.
AC adapter	Check whether power indicator on the device side has lighted up
	before connecting the device between host computer with the USB
	cable.
Interface cable connection	Check that the interface cable is correctly connected to the MO
	drive.
System cable	Check that all cables in the system are correctly connected.
System diagnosis test	Execute the system level diagnostic routines given in the host
	computer manual to further isolate the fault, if possible.
Intermittent or indefinite error	Replace the MO drive if possible. If the faulty condition continues
	after the replacement, the fault will not be caused by the MO drive.
	Refer to the provided hardware and software manuals about the
	system further, for clues of identifying cause of the failure.
