ST15150N/ND/W/WD/WC/DC Product Manual, Rev. D 9 4.4 Installation For option jumper locations and definitions refer to Figures 20, 22, or 24. Drive default mode parameters are not normally needed for installation. Refer to Section 11.3.2 for default mode parameters if you need them. • Ensure that the SCSI ID of the drive is not the same as the host adapter. • If multiple devices are on the bus, set the drive's SCSI ID to one that is not presently used by other devices on the bus. • If the drive is the only device on the bus, attach it to the end of the SCSI bus cable. Internal termination is available on single-ended (ST15150N/ W/WC) drives by enabling this feature with a jumper (see Section 10). External terminators are required for differential (ST15150ND/WD/DC) drives. These external terminators must be provided by the user, systems integrator, or host equipment manufacturer. • If you attach the drive to a bus that contains other devices, and the new drive is not attached to the end of the bus, remove the termination from the new drive. • Set all appropriate option jumpers prior to applying power to the drive. If you change jumpers after applying power, recycle the drive's power to make the new settings effective. Formatting • It is not necessary to low-level format this drive. The drive is shipped from the factory low-level formatted in 512-byte sectors. • Reformat the drive if: a. You select a different sector size. b. You select a different spare-sector allocation scheme.

Installation
For option jumper locations and definitions refer to Figures 20, 22, or 24.
Drive default mode parameters are not normally needed for installation.
Refer to Section 11.3.2 for default mode parameters if you need them.
•
Ensure that the SCSI ID of the drive is not the same as the host adapter.
•
If multiple devices are on the bus, set the drive’s SCSI ID to one that is not
presently used by other devices on the bus.
•
If the drive is the only device on the bus, attach it to the end of the SCSI
bus cable. Internal termination is available on single-ended (ST15150N/
W/WC) drives by enabling this feature with a jumper (see Section 10).
External terminators are required for differential (ST15150ND/WD/DC)
drives. These external terminators must be provided by the user,
systems integrator, or host equipment manufacturer.
•
If you attach the drive to a bus that contains other devices, and the new
drive is not attached to the end of the bus, remove the termination from the
new drive.
•
Set all appropriate option jumpers prior to applying power to the drive.
If you change jumpers after applying power, recycle the drive’s power to
make the new settings effective.
