Seagate DAT Drive Installation Manual 7
Power-on self-test enable/disable (switch S8)
The S8 switch enables or disables execution of power-on
self-test diagnostics when the drive is powered on. If S8 is
ON, the drive responds to SCSI commands only after
successful completion of the self-test (about 5 seconds).
Switches 9 and 10
These switches are only present on DDS-3 drives. They
are reserved and should not be used.
Jumper settings
The configuration jumpers are used to control SCSI bus
termination and terminator power. The jumpers can also
be used for remote SCSI address selection. Figures 4 and 5
show the locations of the jumper blocks for the 3.5-inch
and 5.25-inch internal DAT drives, respectively.
