4.6 Operation Confirmation and Preparation for Use after Installation
C156-E228-02EN 4-15
The BUSY LED is on while the optical disk drive is executing seek,
write, or read operations. The BUSY LED is on momentarily, so it
seems as if it blinked or is off.
The eject motor turns once when the power is turned on so that in
case the spindle motor position deviates due to shocks received by
the drive during transport the position is corrected to allow the
cartridge to be inserted normally. If the cartridge fails to be inserted,
remove the cartridge and turn on the drive power to turn the eject
motor once and reinsert the cartridge.
4.6.2 SCSI connection check
When initial operation checks out normally after the power is turned on, check
whether the drive is correctly connected to the SCSI bus from the host system.
Checking the SCSI connection depends on the host system configuration. This
section describes the general procedure.
(1) Procedure
Figure 4.6 shows the recommended checking procedure.
Note:
Steps a) to c) correspond to a) to c) in Figure 4.6.
a) Issue the TEST UNIT READY command and check that the drive is
connected correctly to the SCSI bus.
b) Use the WRITE BUFFER and READ BUFFER commands to check whether
the SCSI bus operates normally. Use data whose bits change to 0 or 1 at least
once. (Example: A X'00' to X'FF'increment pattern)
c) Check whether the settings are correct. Also, make sure that the controller
and drive operate normally.
