S
CSI 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 3-3. Dell HIP Alert Log Messages
Cause
A failure has occurred with the sys-
tem power supply or voltage
probe(s) on the SCSI backplane
board in the specified server. If pos-
sible, the chassis number and probe
number are also provided.
The voltage probe on the backplane
board or system board has exceeded
its range.

Action
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.
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.
