Before Starting
Perform these preliminary steps before removing and replacing a
FRU.
Step
Action
1
Verify that the symptom is not caused by improper
configuration or a loose cable.
2
Confirm with the customer that data has been backed
up. If not, the data could be lost (when a hard disk is at
fault).
3
Ensure that the operating system is shut down before
turning off the system or halting the CPU.
4
Enter the SHOW CONFIG command and write down the
following information:
—
System ROM version
—
Graphics type
—
Memory configuration
Verify that the configuration agrees with the
amount and type of memory modules present. If
the configuration does not agree, verify that the
memory modules are installed correctly.
—
SCSI devices and IDs
Verify that the configuration agrees with the actual
hardware. If the configuration does not agree, ensure
that the following are true:
SCSI IDs are all unique.
Cables are correctly installed.
The expansion box power is turned on first.
5
Wait three minutes after turning off a monitor before you
