Connecting the disks
You connect hard disks to the LaserWriter IIntx following the standard SCSI procedures. For
each disk you're connecting, you'll need a SCSI peripheral cable. You'll also need a SCSI cable
terminator for the first disk, and an additional terminator for two or more disks. (No system
should include more than two terminators.)
___________________________________________________________
Warning-Each disk must have a unique SCSI ID number. Do not turn on or attempt to use the
printer or any attached hard disk until each disk has been assigned its number.

A SCSI peripheral cable and a SCSI cable terminator
Two hard disks connected to a LaserWriter IIntx
To connect a single hard disk:
1. Attach either end of a peripheral interface cable to the SCSI port on the LaserWriter IIntx.
2. Snap the wire clips on the SCSI port onto the cable.
3. Attach the other end of the peripheral interface cable to either SCSI port on the hard disk.
4. Snap the wire clips on the SCSI port onto the cable.
5. Attach the end of a cable terminator without clips to the other SCSI port on the hard disk.
6. Snap the wire clips on the SCSI port onto the cable terminator.
To connect multiple hard disks:
1. Attach either end of a peripheral interface cable to the SCSI port on the LaserWriter IIntx.
2. Snap the wire clips on the SCSI port onto the cable.
3. Attach the other end of the peripheral interface cable to the clip end of a cable terminator
4. Snap the clips on the cable terminator onto the cable.
5. Insert the other end of the cable terminator onto either SCSI port on the hard disk.
6. Snap the clips on the SCSI port onto the cable terminator.
7. Attach a second peripheral interface cable to the other SCSI port on the hard disk.
8. Attach the other end of the peripheral interface cable to either SCSI port on the next hard
disk.
9. Repeat steps 7 and 8 for each additional hard disk.
10. Attach a cable terminator to the unused SCSI port on the last hard disk.

Chaining different sizes and types of hard disk
You can add different sizes of hard disk to the SCSI chain, but the LaserWriter IIntx must be
able to tell what size a disk is. This is possible with all Apple SCSI hard disks, but not with
some other brands. These disks cannot be connected to the LaserWriter IIntx.
In addition, there should be no more than two terminators in any SCSI chain. If your non-Apple
SCSI hard disk has an internal terminator, you may have to follow the manufacturer's
guidelines to disable it.
