Figure 2. DIP Switch Settings for Internal DAT24 Drives

NOTE: If you change a DIP switch setting, the new setting does not take effect until you restart
the drive or send a SCSI Bus Reset to the drive.
SCSI ID Switches (Switches 1 through 3)
Switches 1, 2, and 3 correspond to the SCSI device address identification bits 0 (least-significant
bit), 1, and 2 (most-significant bit), respectively. The default setting is SCSI ID 0 (all three switches
OFF).
NOTE: Each SCSI device on a bus must have a unique SCSI ID. The SCSI host controller gener-
ally uses ID 7. In some systems, the boot drive uses ID 0.
