Degraded
BIOS detected
1.
Unable to use all of the installed memory (more than one DIMM
installed).1
2.
In a mirrored configuration, when memory mirroring takes place
and system loses memory redundancy. This is not covered by
(2). 1
3.
PCI Express* correctable link errors.
Integrated BMC detected
1.
Redundancy loss such as a power supply or fan. Applies only if
the associated platform subsystem has redundancy capabilities.
2.
CPU disabled
–
if there are two CPUs and one CPU is disabled.
3.
Fan alarm
–
Fan failure. Number of operational fans should be
more than minimum number needed to cool the system.
4.
Non-critical threshold crossed
–
Temperature, voltage, power
nozzle, power gauge, and PROCHOT2 (Therm Ctrl) sensors.
5.
Battery failure.
6.
Predictive failure when the system has redundant power
supplies.

Non-Fatal
Non-fatal alarm
–
system is likely to fail:
BIOS Detected
1.
In non-mirroring mode, if the threshold of ten correctable errors
is crossed within the window.1
2.
PCI Express* uncorrectable link errors.
Integrated BMC Detected
3.
Critical threshold crossed
–
Voltage, temperature, power nozzle,

Fatal alarm
–
system has failed or shut down:
BIOS Detected
1.
DIMM failure when there is one DIMM present and no good
memory is present.1
2.
Run-time memory uncorrectable error in non-redundant mode.1
3.
CPU configuration error (for instance, processor stepping
mismatch).
Integrated BMC Detected
1.
CPU CATERR signal asserted.
2.
CPU 1 is missing.
3.
CPU THERMTRIP.
4.
No power good
–
power fault.
5.

Notes:
1.
The BIOS detects these conditions and sends a
Set Fault Indication
command to the Integrated BMC to provide
the contribution to the system status LED.
