Basics SCSI Devices - 9

SCSI Devices

SCSI ID Numbers

The PowerBook Duo Dock supports up to six SCSI devices. To
avoid conflicting SCSI ID numbers, assign external SCSI
devices numbers between 2 and 6. (The hard drive inside the
PowerBook Duo has SCSI ID number 0, and, if installed, the
hard drive inside the Duo Dock has ID number 1.)

Note:

You must use an HDI-30 SCSI system cable to connect

external SCSI devices to the Duo Dock.

Caution:

power to all devices in the chain.

When making SCSI connections, always switch off

Basics SCSI Devices - 10

SCSI Termination

The PowerBook Duo Dock has a built-in SCSI terminator.

To terminate a SCSI chain connected to the dock, attach one
external terminator only to the last device in the chain, or
connect a SCSI device with built-in termination as the last
device in the chain.

Note:

SCSI devices from other vendors may have built-in
terminators. If a SCSI device with a built-in terminator is
the last device in the chain, do not add an external
terminator to that device. If more than one SCSI device in the
chain has built-in terminators, you may need to remove the
extra internal terminators.
