Terminating the SCSI Bus and Providing Terminator Power (Jumper # 6)

ENABLE  termination if this drive:

Do NOT ENABLE  termination if this drive:

Enabling Auto Start Delay and Delay Start 6/12 (Optional) (Jumper #9 / #10)

If you place a jumper in position #5 to disable autom.-spin up, the SCSI controller ignores the jumpers for delaying the autom. start (pos. 9 and 10).

You can delay the autom. spin up of the SCSI hard disk drive when the device draws power supply current. Using this option, the hard disk drive delays spin upby a period of time multiplied by the SCSI address. You control wheter the period of time is 6 or 12 seconds for this calculation.

Disabling Unit Attention Conditions (Optional) (Jumper #7)

Skip this step if the SCSI controller wants the hard disk drive to build unit attention information. The default setting is unit attention enabled, no jumper in 7.

If you place a jumper in pos.-7 the drive will not enter a unit attention condition for commands immediately following power-on of the computer, or SCSI bus reset.

Connecting a Drive Activity LED (Position #12)

The upper pin supplies +5Vdc to the (anode) LED. Be sure that the LED you select can handle a current of appr. 8mA.
