Delay Auto Start
This jumper asks the drive to start automatically, but after waiting for a predefined number of seconds from the time power is applied / ON. This is also used to offset motor startup load on systems that have many drives.
Stagger Spin
An enhanced version of "Delay Auto Start" is stagger pin. When a system equipped with many hard drives have this option set for each unit, the drives stagger their startup time by multiplying a user-defined constant time with their SCSI device ID. This is to be sure that no two drives on the same SCSI channel starts up simultaneously.
Narrow/Wide
Some drives are provided with a jumper to control whether they will function in narrow or wide mode.
Force SE
Makes newer Ultra2, Wide Ultra2, Ultra 160, Ultra160+ or other LVD SCSI drives to be forced to use single-ended (SE) operation instead of low voltage differential (LVD).
Disable Parity
Parity checking on the SCSI bus is turned off.
