Apple Macintosh PowerBook 190 Series - Manual (Page 67)

10 If there are no SCSI devices currently connected to the other computer, attach a SCSI
system cable to the other computer. Make sure you have a terminator connected to your
PowerBook. If there are SCSI devices currently connected to the other computer, attach
a SCSI peripheral interface cable to the last device in the SCSI chain.
11 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. If the last
device is not internally terminated, make sure you connect a terminator to
your PowerBook (or whichever device is last in the SCSI chain).
12 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 Always shut down the Macintosh PowerBook before
connecting or disconnecting the SCSI disk adapter cable. Connecting
the adapter cable while the computer is turned on can damage the
computer.
