TP TP (Not applicable to "WC" model drives)

Off Off No terminator power is connected to drive

terminators or SCSI bus I/O pin 26.

On Off Drive supplies its own terminator power only.

Jumper on this position is factory default.

Off On Drive supplies power to I/O pin 26 of SCSI bus;

none to internal terminators. When drives have

differential I/O circuits a jumper on the right TP

position may be needed to power external

terminator (see system documentation). The

Hawk 2 family ST12400WD drive has differen-

tial I/O circuits which have no terminator cir-

cuits on the drive.

On On Drive supplies terminator power to itself (inter-

nal connection) and to I/O pin 26 of SCSI bus.

This is a legal jumper setting.

TP Position A

On This horizontally positioned jumper across the

two TP positions nearest PCB edge, connects

terminator power from SCSI bus I/O pin 26 to

the drive's internal terminators (for single-ended

I/O only).

Off See above explanations for TP jumpers.
