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.
