Apple Power Macintosh 4400 - Manual (Page 58)

IMPORTANT The material that follows—“Before You Connect a Device”
and “Connecting a SCSI Device”—contains general instructions for attaching
SCSI devices to your computer. Make sure you also follow the specific
instructions that came with the SCSI device you are connecting to
your Macintosh.
Before you connect a device
Before you connect a SCSI device to your Macintosh, complete these tasks:
m Make sure each SCSI device connected to your Macintosh has its own
unique ID number from 0 to 6. The computer itself (the main logic board
inside it) has the ID number 7, making the ID numbers 0 through 6
available for additional SCSI devices. Make sure other SCSI devices you
add to the chain do not use ID number 7. See the instructions that came
with each SCSI device for information on checking and setting its SCSI
ID number.
IMPORTANT If you use two or more devices attached to the same SCSI
interface with the same ID number, your equipment could malfunction and
you could lose data as a result.
m Make sure you have the appropriate cable for attaching the SCSI device to
your Macintosh.
If the device is the first or only one you’re connecting, use a SCSI system
cable to connect it to the computer’s SCSI port:
