N drives

Terminating the drive

ST423451N 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 (see Figure 7). If you install the drive on the end of the SCSI bus, enable ter- mination by installing a jumper on pins 19 and 20 of connector J4A.
