Connecting an External SCSI Device
Before you connect any external SCSI devices to the computer’s
built-in external SCSI device port, read Chapter 4 of the
User’s Guide for instructions on setting the SCSI ID numbers
and properly terminating your SCSI devices.
Then connect the first external device to the external SCSI
device port.
See Chapter 4 of the User’s Guide and the documentation that
came with your SCSI devices for information on cabling the
SCSI devices to each other.
