How to install the drive
This installation guide provides step-by-step instructions to make
your drive installation as easy as possible. Follow the installation
steps listed for your drive model as listed below:
ST150176LW (use the installation steps beginning below).
ST150176LC (use the installation steps beginning on page 30).
ST150176LW installation
1. Set the SCSI ID on the drive.
Determine which SCSI IDs are already being used in the
system and then assign this disc drive a SCSI ID that isn’t
already being used. Use the J6 connector located on the
front of the drive to set the SCSI ID (see Figure 3).
• This drive is SCAM (SCSI Configured Auto Mati-
cally) compliant. If you are installing this drive in a
SCAM compliant system, you can skip this step
because the system automatically assigns the drive SCSI
ID.
• The host system’s SCSI controller usually uses SCSI ID 7
so this SCSI ID is not usually available for disc drives or
other devices.
• Most ST150176LW drives are factory set with the SCSI ID
set at 0. If this is the only SCSI drive in your system and
there are no other SCSI devices on the daisychain, you can
leave this drive’s SCSI ID set to 0 and proceed to the next
step. A device is any hardware other than an inline termina-
tor that is connected to the SCSI cable.
