The hard-disk drive bays provide space for up to three 1-inch, hot-pluggable
SCSI hard-disk drives.
Figure 4-7 provides an internal chassis view of the hard-disk drive bays, the
1 x 3 hot-pluggable SCSI backplane board, and the Ultra2/low-voltage differen-
tial (LVD) SCSI cable. The Ultra2/LVD SCSI cable has two connectors:
 The connector at one end attaches to the Ultra2/LVD SCSI host adapter
connector labeled “PRIMARY SCSI-A” on the system board, or to an
optional SCSI host adapter card such as the Dell PowerEdge Expandable
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.
Remove a SCSI hard-disk drive from a hard-disk drive bay as follows:
1. If the system has a PowerEdge Expandable RAID Controller installed, take
the hard-disk drive off-line using the PowerEdge RAID Console utility. If the
system has no PowerEdge Expandable RAID Controller installed, shut
down the system.
Refer to the PowerEdge Expandable RAID Controller documentation for
information about using the PowerEdge RAID Console utility.
