Connecting The Floppy Disk Drive
Connect the SCSI floppy disk drive to the SCSI port of your
SPARCbook. You can use the remaining (female) connector on the rear
of the floppy drive to connect another SCSI device, if required.
ò
Setting the SCSI ID Switches
Like all SCSI devices, your floppy drive must have a unique SCSI ID.
You set the SCSI ID for your floppy drive using the three SCSI ID
switches shown in Figure 7-3. In order to avoid conflicts with other
devices, it is recommended that you set the SCSI ID to 5.
Note
The switches on the floppy drive are wired internally for “active low” operation. This
results in the position labeled on the switch as “ON” corresponding to binary 0 (zero).
