3.10 Dismounting Drive
C156-E205-01EN 3-23
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.
3.9.2 Connection check
When initial operation check terminates normally after the power is turned on,
check whether the drive is correctly connected by issuing command from the host
system. Checking procedure depends on the host system configuration.
If processing terminates abnormally:
a) If sense data has been obtained by the REQUEST SENSE command, analyze
the sense data. If the error is recoverable, retry the processing.
b) Check the following items for AT interface cable connection:
! All connectors, including other devices, are connected correctly.
! Make sure the correct cable is being used (whether it corresponds with
the cable selection mode).
c) Make sure again that the jumper settings are correct.
3.10 Dismounting Drive
How to demount an optical disk drive (for setting terminal checking, setting
change, or device replacement) depends on the system cabinet configuration.
Determine the demounting procedure in consideration of the requirements of each
system. This section describes the general demounting procedure and notes on
demounting drives.
Device damage: Before demounting the optical disk drive, turn
off the system power. Do not remove screws securing the cables
and drive when the power is on.
1) Remove the power cable.
2) Remove the AT interface cable.
3) Remove the DC ground cable.
