DIP switches
The MO drive has four DIP switches on the rear of the
drive. The following explains the functions and
default setting.
DIP switch 1:
• Device type mode (Default Setting: off)
This switch configures the MO drive as either an optical storage device or a hard disk drive device. When
using your MO drive with any of its supported operating systems, we recommend that you use the default
setting, optical storage device.
Some other operating system environments may require this switch be set to hard disk type (on position).
Consult your operating system documentation for details.
DIP switch 2:
• Automatic spindle stop mode (Default Setting: on)*
When this setting is on, the drive automatically stops the disk to save power when not in use.
When this setting is off, the drive keeps the disk rotating while the MO drive is on.
* Not assigned for DynaMO 2300 SCSI.
In the case of DynaMO 2300 SCSI, the drive automatically stop the disk to save power when not in use,
regardless of this setting on/off.
DIP switch 3:
• Write cache mode (Default Setting: on)
The MO drive has 2 MB internal cache. Best write performance can be achieved by the default setting
(on).
DIP switch 4:
• Terminator mode (Default Setting: on)
If your MO drive is the last device of your SCSI chain, uses the drive with the default setting on. If your
MO drive is in the middle of the SCSI chain, or you terminated your SCSI chain with an external
terminator, move this switch to the off position.
Under extreme circumstances, such as very dirty environments, write cache enable may cause disk
corruption.
If you use your MO drive under these extreme circumstances, we recommend this switch be set to off.
If your SCSI chain has more than one terminator, communication errors may occur.
Terminator mode (Turn it off if the MO drive
is not the end device in the SCSI chain.)
Write cache (ON = activated)

Automatic spindle stop mode (On - activated)
Not assigned for DynaMO 2300 SCSI.
(The switch is set to off.)
