Figure2-5. Power Supply Features; Table 2-1. Scsi Hard-Disk Drive Indicator Patterns - Dell PowerEdge 2500 Installation And Troubleshooting Manual

Table 2-1 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 the integrated PERC3/Di, or an optional PERC3/DC or PERC3/QC controller installed, you will see only the "drive online" and
"drive bay empty" indicator patterns.
