3.9 Post-installation Operation Check and Preparation for Use
C156-E227-01EN 3-25
(2) Items to confirm if an error occurs in initial self-diagnostics
•
Make sure that the cables are correctly connected.
•
Make sure that the power voltage is supplied normally. (Measure the voltage
at the power supply connector of the optical disk drive.)
•
Make sure that all of the setting terminals are correctly set.
•
Continuous blinking of the LED on the front panel indicates that an error has
been detected during initial self-diagnostics. Fujitsu recommends issuing,
wherever possible, the REQUEST SENSE command from the initiator (host
system) to collect information (sense data) for error analysis.
The LED is on while the optical disk drive is performing the seek,
write, or read operation. However, because an LED goes on only
momentarily, it may seem to blink or remain off.
Upon power-on, the eject motor turns once to correct the position of
the eject motor (in case it deviates due to shock or vibration applied
to the drive during transportation), and allows a cartridge to be
inserted normally.
If you cannot insert a cartridge properly, remove the cartridge and
turn on the drive power to have the eject motor turn once before
reinserting the cartridge.
3.9.2 Connection check
When the initial operation check terminates normally after power-on, check
whether the drive is correctly connected by issuing a command from the host
system. The checking procedure depends on the host system configuration. The
following describes a general check procedure.
(1) Check to be made if the initial operation check terminates abnormally:
a) Analyze sense data if any has been collected due to the REQUEST SENSE
command. If the error is recoverable, retry the processing.
b) On AT interface cable connections, make sure that:
•
All connectors, including those of other devices, are correctly connected.
•
Correct cables are being used (whether they support the cable selection mode
setting).
c) Reconfirm that the jumper wire settings are correct.
