About This Guide

This document describes installing and configuring an optional fifth SCSI hard-disk drive
in your Dell™ system's peripheral bay.
Before You Begin
Before installing a fifth SCSI hard-disk drive, you should install and configure the other four
SCSI drives. If you want to set up the five drives in a split 1 x 2 and 1 x 3 configuration, you
must install a second, optional SCSI backplane daughter card in your system. (For more
information about the daughter card, see "Installing Hard-Disk Drives" in your system's
Installation and Troubleshooting Guide.) Figure 1-1 illustrates the system components
associated with the SCSI hard-disk drives.
