Possible Problems
Step 3. Display and examine the system event log (SEL) and forward progress log (FPL) for further
information relating to warning or fault isolation.
Step 4. Review the firmware revisions of all firmware.
NOTE
Step 5. Use the iLO MP command to cycle the server power: pc off, pc on, or pc -cycle.
Step 6. Turn the server off, wait at least twenty seconds, then turn the server back on to see if the failure
can be cleared.
Step 7. Check that all DIMMs are seated properly.
Step 8. Check that the DIMM configuration on the I/O baseboard matches those approved. A minimum of
one DIMM pair must be installed.
Step 9. Verify that the DIMMs are fully seated. When the DIMM is fully seated in the mating connector,
the retaining latches are closed (they should be flush with the front of the DIMM). If the latches are
not closed, reseat the DIMM fully by engaging the retaining latches and closing them fully.
Step 10. Check that the processors are installed in the correct sockets on the processor extender board. See
Figure 4-13 on page 56 for the correct processor load order.
Step 11. Verify the processors are of the same type.
Step 12. Check the boot order with the SCSI configuration utility.
Step 13. Check the switch settings on the I/O baseboard. They should match Figure 4-24 on page 69.
Step 14. If there are no obvious errors, reflash the BMC firmware. (See Appendix C, "Utilities," on page 161.)
Step 15. If the server will still not boot, it may be necessary to replace the base unit.

The Server Has Intermittent Failures

Step 1. Examine the front panel LEDs for warning or fault indications. The server LED flashes yellow with
a warning indication and flashes red with a fault indication. See "Front Control Panel LED
Indicators" on page 117.
Step 2. Examine the QuickFind Diagnostic Panel for indications of specific warning or fault indications.
The diagnostic LEDs present patterns that categorize the source of the warning or fault. See
"QuickFind Diagnostic Panel LED Indicators" on page 119.
Step 3. Display and examine the errdump logs for further information relating to warning or fault
indications.
Step 4. Display and examine the system event log (SEL) and forward progress log (FPL) for further
information relating to warning or fault indications.
Step 5. Make sure that the server fan assemblies are fully seated.

If the server does not boot to EFI, the only way to check firmware revisions is with
the iLO MP SR command. However, the result may not be accurate because the
versions it displays are updated by system firmware during the boot to EFI. If the
system firmware does not boot to the point where it updates iLO MP firmware
version, the versions displayed by the SR command may not be correct.
