If a 1 x 6 hot-pluggable SCSI backplane board is installed in the system, three light-
emitting diode (LED) indicators adjacent to each of the six SCSI hard-disk drive bays
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, fol-
lowed 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.
