Connecting SCSI devices to your PowerBook involves these steps:
m installing software
m setting SCSI ID numbers
m checking that the SCSI chain is properly terminated
m connecting cables
These steps are described in the following sections.
Installing software
Many SCSI devices come with software that allows your computer to
communicate with them. These programs are called drivers. (If no drivers
come with a device, then it doesn’t need any.) To install a driver, follow the
instructions that came with the device.
Setting SCSI ID numbers
Each device in a SCSI chain must have a unique ID number between 1 and 6
so the computer can identify it properly.
Your computer has the SCSI ID number 7, and its internal hard disk has the
number 0.
The ID numbers of Apple SCSI devices can be set as follows.
1Make sure the SCSI device is turned off.
If the device is already part of a SCSI chain, make sure that all devices in the
chain are turned off, including the computer.
WARNING
Using two or more devices with the same SCSI ID number
can cause your equipment to malfunction. You could lose information
as a result.
