J2
jumper
installation		Jumper function description
SE
On		Forces drive to use single-ended I/O drivers/receivers only.
Off		Drive can operate on the interface in low voltage differential mode or single-ended, depend-
		ing on the voltage state of the I/O “DIFFSNS” line. Default is SE jumper not installed.
DS	ME
Off	Off	Spindle starts immediately after power up - Default setting.
Off	On	Drive spindle does not start until Start Unit command received from host.
On	Off	Spindle Startup is delayed by SCSI ID times 12 seconds after power is applied, i.e., drive 0
		spindle starts immediately when DC power connected, drive 1 starts after 12 second delay,
		drive 2 starts after 24 second delay, etc.
On	On	Drive spindle starts when Start Unit command received from host. Delayed start feature is
		overridden and does not apply when ME jumper is installed.
WP
On		Entire drive is write protected.
Off		Drive is not write protected. Default is WP jumper not installed.
PD
On		Parity checking and parity error reporting by the drive is disabled.
Off		Drive checks for parity and reports result of parity checking to host.
		Default is PD jumper not installed.
RES
Off		Reserved jumper position. Default is no RES jumper installed.
TP1		(Does not apply to LC/LCV model)
Off		The drive does not supply terminator power to external terminators or to the SCSI bus I/O
		cable.
On		Drive supplies power to SCSI bus I/O cable. When drives have differential I/O circuits, a
		jumper on the TP1 position may be needed to power external terminators (see system docu-
		mentation). These drives do not have terminator circuits on the drive.
