Power Supply Indicators - Dell PowerVault 735N Service Manual

Codes and Error Messages: Dell PowerVault 735N Systems Service Manual
Table 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.
