Description
Green
Solid on
Ok
System ready
Green
~1 Hz blink
Degraded
BIOS detected
 Unable to use all of the installed memory (more than one
DIMM installed).
1
 In a mirrored configuration, when memory mirroring takes
place and system loses memory redundancy. This is not
covered by (2).
1
 PCI Express* correctable link errors.
Integrated BMC detected
 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.
 Fan alarm – Fan failure. Number of operational fans should
be more than minimum number needed to cool the system.
 Non-critical threshold crossed – Temperature, voltage,
power nozzle, power gauge, and PROCHOT2 (Therm Ctrl)
sensors.
 Battery failure.
 Predictive failure when the system has redundant power
supplies.
Amber
~1 Hz blink
Non-Fatal
Non-fatal alarm – system is likely to fail:
BIOS Detected
 In non-mirroring mode, if the threshold of ten correctable
errors is crossed within the window.
1
 PCI Express* uncorrectable link errors.
Integrated BMC Detected
 Critical threshold crossed – Voltage, temperature, power
nozzle, power gauge, and PROCHOT (therm Ctrl) sensors.
 VRD Hot asserted.
 Minimum number of fans to cool the system are not present
or have failed.
Amber Solid on Fatal Fatal alarm – system has failed or shutdown:
BIOS Detected
 DIMM failure when there is one DIMM present and no good
memory is present.
1
 Run-time memory uncorrectable error in non-redundant
mode.
1
 CPU configuration error (for instance, processor stepping
mismatch).
Integrated BMC Detected
 CPU CATERR signal asserted.
 CPU 1 is missing.
 CPU THERMTRIP.
 No power good – power fault.
 Power Unit Redundancy sensor – Insufficient resources
offset (indicates not enough power supplies are present).

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.
2. Support for an upper, non-critical threshold limit is not provided in default SDR configuration. However if a
user does enable this threshold in the SDR, then the system status LED should behave as described.
