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.

Table 35. System Status LED

System Status
System ready
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.
CPU disabled – if there are two CPUs and one CPU is disabled.
2.
Fan alarm – Fan failure. Number of operational fans should be
3.
more than minimum number needed to cool the system.
Non-critical threshold crossed – Temperature, voltage, power
4.
nozzle, power gauge, and PROCHOT2 (Therm Ctrl) sensors.
5. Battery failure.
6. Predictive failure when the system has redundant power
supplies.
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
Critical threshold crossed – Voltage, temperature, power nozzle,
3.
power gauge, and PROCHOT (therm Ctrl) sensors.
4. VRD Hot asserted.
5. Minimum number of fans to cool the system is not present or
have failed.
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.
No power good – power fault.
4.
Power Unit Redundancy sensor – Insufficient resources offset
5.
(indicates not enough power supplies are present).
