Terminating the SCSI Bus and Providing Terminator Power (Jumper # 6)
ENABLE termination if this drive:
- is the only drive in the computer or storage enclosure
- is the last device on a computer or storage enclosure.
Do NOT ENABLE termination if this drive:
- is going inta a computer or storage enclosure that has one or more
drives already installed, and this drive will not be the last device
on the SCSI chain.
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.
- For a start delay of 6 seconds multiplied by the SCSI address, place a jumper in position 9 (auto-
- For a start delay of 12 seconds multiplied by the SCSI address, place jumpers in position 9 (auto-start
-delay and 10 (delay-start-6/12).
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
