Apple PowerBook (Duo, 2300 Series) - Manual (Page 110)

m When you use SCSI disk mode, the computer should display an icon with a
number in it.
If the computer starts up normally, immediately press the Power key to shut
down (if you can) or turn off the computer. If you don’t, you might damage
your information or equipment.
m Make sure you are using the correct cable for SCSI disk mode. The HDI-30
SCSI Disk Adapter is about 10 inches long, is dark gray, and has 30 pins in
the connector (no “missing” pins). Do not use the HDI-30 SCSI System
Cable, which is light gray, is about 20 inches long, and has 29 pins in the
connector (one “missing” pin). That cable is for connecting SCSI
equipment to a Duo Dock Plus or a Duo MiniDock.
m Check that all cable connections are secure.
m The PowerBook’s battery may be drained. Plug in the power adapter and
let the battery charge for a few minutes. Then press the Power key on the
PowerBook’s keyboard to restart it, and restart the other Macintosh.
m Start up the other Macintosh with the Disk Tools disk that came with it (do
not use the disk that came with your PowerBook). If the connection works,
then a system software extension on the other Macintosh may be causing
the problem.
When I start up using SCSI disk mode, I see a flashing question mark icon.
m Make sure you are using the correct cable for SCSI disk mode. The HDI-30
SCSI Disk Adapter is about 10 inches long, is dark gray, and has 30 pins in
the connector (no “missing” pins). Do not use the longer, light gray HDI-30
SCSI System Cable.
m Make sure terminators are placed correctly in the SCSI chain. See
“Connecting SCSI Devices” in Chapter 3 for more information.
