Three indicator lights in each SCSI hard-disk drive carrier provide information
on the status of the SCSI hard-disk drives (see Figure 3-1). The SCSI backplane
firmware controls the drive online and drive failure indicators.

Table 3-4 lists the drive indicator patterns established by the SCSI backplane
firmware. Different patterns are displayed as drive events occur in the system.
For example, in the event of a hard-disk drive failure, the
drive failed
pattern
appears. After the drive is selected for removal, the
drive being prepared for
removal
pattern appears, followed by the
drive ready for insertion or removal
pattern. After the replacement drive is installed, the
drive being prepared for
operation
pattern appears, followed by the
drive online
pattern.
NOTE: If you do not have a Dell PowerEdge Expandable RAID Controller host
adapter card installed, you will see only the drive online and drive bay empty
indicator patterns.
