7.2.1 Jumper signal description on J6

7.2.1.1 Position #1-2
! Enable Auto Spin Up (68-pin model)
If a jumper is installed, the drive will spin up automatically after power on reset. If a jumper is not
installed, the drive will not spin up unless a START UNIT command is received.
! Disable Auto Spin Up (80-pin model)
If a jumper is not installed, the drive will spin up automatically after power on reset. If a jumper is
installed, the drive will not spin up unless a START UNIT command is received.
7.2.1.2 Position #3-4 and #5-6: Auto Start Delay & Delay Start 6/12
These pins control when and how the drive spins up with the combination of Position #1-2 on J6. When
both Auto Spin up and Auto Start Delay are enabled, the drive start will be delayed by a period of time
multiplied by its own SCSI address. If Auto Spin up is disabled, these jumpers will be ignored. Placing a
jumper on delay start 6/12 results in a start up delay of 12 seconds times the SCSI ID.
Note: In the table below, 'on' means a jumper is installed and 'off' means that a jumper is not installed.
