Installation

For option jumper locations and definitions refer to Figure 10.1-1. Drive default mode parameters are not nor-
mally needed for installation. Refer to Section 11.3.2 for default mode parameters if they are needed.
•
Ensure that the SCSI ID of the drive is not the same as the host adapter. Most host adapters use SCSI ID 7.
•
If multiple devices are on the bus set the drive 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. Permanently installed
terminators must be enabled on the drive for ST12400N models using a jumper plug (see Figure 10.1-1), For
ST12400ND models, terminators must be installed external to the drive. These external terminators must be
provided by the user, systems integrator or host equipment manufacturer.
•
If the drive is attached to a bus that contains other devices, and the new drive is not attached to the end of the
bus, the terminator enable jumper should be removed from the new drive.
•
Set all appropriate option jumpers for desired operation prior to power on. If jumpers are changed after power
has been applied, recycle the drive power to make the new settings effective.
Installation instructions are provided by host system documentation or with any additionally purchased drive
installation software. If necessary see section 14.0 for Seagate support services telephone numbers.
