Checking that the SCSI chain is properly terminated

To ensure accurate transmission of information, a chain of SCSI devices must have a terminator at each end. Terminators are built into some SCSI devices.

SCSI terminator

mThe Duo Dock and the Duo MiniDock both have built-in terminators.

mExternal SCSI devices from Apple do not have built-in terminators.

mExternal SCSI devices from other vendors may have built-in terminators; see the documentation that came with the device.

What these facts mean to you: You do not need to add a terminator at the beginning of the chain. You need to make sure that the last device in the chain has an internal or external terminator, and that no other devices have terminators.

If you are attaching one SCSI device

Make sure that there is one of the following:

man internal terminator in that device

man external terminator attached to that device

If you are attaching more than one SCSI device

Make sure that both of these conditions exist:

man internal terminator in, or an external terminator attached to, the last device

mno other terminators (internal or external) in the chain

If you have too many devices with internal terminators, your Apple- authorized service provider can remove extra terminators.

SCSI chain configurations are shown in the illustration on the following page.
