Check the power supply and SCSI backplane board connections. If the power supply is connected properly, replace the power supply (or, if pos- sible, switch it with another power supply that is working properly to determine whether the power supply is the problem). See “Replacing a Power Supply in Chapter 7. If the problem persists, see Chapter 11, “Getting Help,” for instructions on obtaining technical assistance.

If the problem persists, check the SCSI backplane board connections. If the power supply is connected properly, replace the power supply (or, if possible, switch it with another power supply that is work- ing properly to determine whether the power supply is the problem). If the problem persists, see Chapter 11, “Getting Help,” for instructions on obtaining technical assistance.

SCSI Hard-Disk Drive Indicator Codes

The 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. The SCSI backplane firmware controls the drive online and drive fault indicators, while the drive access indicator is usually controlled by the drive itself.

Table 3-4 lists the drive indicator patterns established by the SCSI backplane firmware. Different patterns are dis- played 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, then the “drive online” pattern.
