SCSI bus termination

Terminating the drive

ST446452W drives are terminated with permanently mounted IC
active terminators. If you install one of these drives and it is not
on the end of the SCSI bus, disable the terminators by removing
the TE jumper from pins 19 and 20 of connector J4A. If you
install the drive on the end of the SCSI bus, enable termination
by installing a jumper on pins 19 and 20 of connector J4A (see
Figure 4).
