This chapter describes how to install and configure small computer system interface
(SCSI) hard-disk drives in the computer's internal hard-disk drive bays. Instructions are
also included for upgrading the system by installing a Dell host adapter card .
The hard-disk drive bays provide space for up to three 1-inch hard-disk drives.
Figure 10-1 illustrates the hard-disk drive bays, the 1 x 3 hot-pluggable SCSI backplane
board, and the Ultra2/low-voltage differential (LVD) SCSI cable. The Ultra2/LVD SCSI
cable has two connectors:
The connector at one end attaches to the Ultra2/LVD SCSI host adapter connec-
tor labeled "PRIMARY SCSI-A" on the system board, or to an optional SCSI host
adapter card such as the Dell PowerEdge Expandable redundant array of inexpen-
sive disks (RAID) Controller host adapter card.
The connector at the other end of the cable attaches to the connector labeled
"SCSI" on the SCSI backplane board.
NOTE: If you should ever disconnect any or all of the interface cables from the system
board, be sure to note the order in which you remove them so that you can reinstall
them in the correct order. Refer to "Routing the Interface Cables Inside the Chassis"
in Chapter 8 for more information about installing the interface cables.
