Apple PowerBook (2400c) - Manual (Page 53)

10 Connect the large connector on the Apple HDI-30 SCSI Disk Adapter cable to a SCSI
cable attached to the SCSI port on the last device in the SCSI chain, or to the SCSI
system cable on the other computer.
If the last device in the chain has an internal terminator, disconnect the
device and connect the PowerBook before it in the SCSI chain.
11 Turn on the PowerBook by pressing the Power key.
After a few seconds a SCSI icon appears on the screen, showing the ID
number you assigned in step 3.
WARNING If you do not see the SCSI icon, and the computer starts up
normally or displays an error message, press the Power key to shut down
(if you can) and then immediately disconnect your computer from the
SCSI chain. (If you can’t choose Shut Down, try pressing the reset
button. If you cannot shut down your Macintosh PowerBook, you
should disconnect the cable anyway, or you may lose information.)
Then go back and repeat steps 6 through 10, making sure to use the
proper cables.
You may not be able to have password protection turned on in the
Password Security control panel while using your PowerBook in
SCSI disk mode. Turn password protection off if you experience
problems. See “How do I turn password security on and off?” in the
“Setting Options” topic area of Mac OS Guide, available in the
Guide (h) menu.
WARNING Always shut down the PowerBook before connecting or
disconnecting the SCSI disk adapter cable. Connecting the adapter cable
while the computer is turned on can damage the computer.
