Apple PowerBook (200 Series) - Manual (Page 45)

Remove the terminator from the last device before connecting the
PowerBook. (If the last device has an internal terminator, disconnect the
device and connect the PowerBook to the end of the SCSI chain. An Apple-
authorized service provider can remove the terminator.)
10 Turn on the PowerBook by pressing the power button.
After a few seconds a SCSI icon appears on the screen, showing the ID
number you assigned in step 3.
11 Turn on the other SCSI devices in the chain, if any.
12 Turn on the other computer.
The PowerBook appears as a hard disk icon on the desktop of the computer
you connected it to. You can now transfer and use files as if the PowerBook
were an external disk drive.
WARNING If you do not see the SCSI icon, and the computer starts
normally or displays an error message, choose 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 power button. If you
cannot shut down your 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.
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.
