4)  After each cable connector is connected, secure the cable so that the cable 

does not touch the drive or the parts on the PCA or obstruct the flow of 
cooling air in the system cabinet. 

 

1)  Be careful of the insertion directions of SCSI connectors.  For a 

system in which the terminating resistor power is supplied via 
the SCSI cable, connecting connectors in the wrong direction 
may cause the following: 

 

The overcurrent protection fuse of the terminating resistor 
power supply (SCSI device) may blow when power is turned 
on.  

 

The cable may burn if overcurrent protection is not provided. 

2)  Be careful of cable connector positions when connecting more 

than one SCSI device. The SCSI device having the terminating 
resistor must be connected to the end of the cable. 

3)  The cables must be kept away from the rotating part of the 

spindle motor. 

This section provides the operation check procedures after the power is turned on. 

(1)  Initial operation when the power is turned on 

• 

When the power is turned on, the drive starts initial self-diagnosis.  The LED 
on the front panel is on for 1 second during initial self-diagnosis. 

• 

If an error is detected during initial self-diagnosis, the LED on the front panel 
blinks. 

• 

In case of not inserted the cartridge, when the power is turned on, the eject 
motor automatically turns once. 

(2)  Checks if errors occur at initial self-diagnosis 

• 

Make sure that the cables are connected correctly. 

• 

Make sure that the supply voltage is correct.  (Measure the voltage at the 
power supply connector of the optical drive.) 

• 

Make sure that the settings of all terminals are correct. 

• 

If the LED on the front panel blinks continuously, an error was detected 
during initial self-diagnosis.  In this case, issue the REQUEST SENSE 
command from the initiator (host system) to obtain sense data for error 
analysis.
