RZ28 Fixed Disk Drive: SCSI ID Settings and Hardware Specifications
EK–VX468–IN. A01
August 1993
Introduction
This document provides the SCSI ID settings and lists the hardware
specifications for the RZ28 fixed disk drive. Use the instructions in your
system’s options guide to install the RZ28 fixed disk drive, and for information
on choosing a SCSI ID setting.
Setting the SCSI ID
Before you install the RZ28 fixed disk drive in the system unit, you need
to verify the position of the removable electrical jumpers on the drive. The
position of the jumpers determines the drive’s SCSI ID address.
Your fixed disk drive may have been shipped with all of the jumpers attached
(to prevent loss of jumpers during shipping and unpacking). In this case, the
SCSI ID is set to 7, and you will need to change it.
Set the SCSI ID as shown in Figure 1. Save any jumpers you remove. You
may need them later.
