(2) 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 SCSI cable connection:
All connectors, including other SCSI devices, are connected correctly.
A terminating resistor is correctly mounted at both ends of the cable.
Power is supplied to the terminating resistors correctly.
c) Check the settings of all terminals are correct. Note that the procedure of

4.7 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.
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 SCSI cable.
3) When an external operator panel is mounted, remove its cable. If it is difficult
to access the connector, remove the cable after step e).
4) Remove the DC ground cable.
5) Remove the four screws securing the drive, then remove the drive from the
system cabinet.
6) When storing or transporting the drive, put the drive into an antistatic bag.
