7.2.1.2 Position #3-4 and #5-6 on J6
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 shunt jumper is installed and 'off' means that a shunt jumper is not
installed.
