When AC power is first applied to the system, the status LED will turn solid amber, to indicate that the BMC is booting.
If, upon completing the boot, the BMC does not detect abnormal conditions, the LED will turn off until the system is
commanded-on.
The LED state information below is dependent on the underlying sensor support.
Table 174. System Status LED Indicator States
Color State Criticality Description
Green Solid on OK System booted and ready
Green ~1 Hz blink Degraded System degraded:
x Non-critical temperature threshold is asserted.
x Non-critical voltage threshold is asserted.
x Non-critical fan threshold is asserted.
x Fan redundancy is lost; sufficient system cooling is maintained.
This does not apply to non-redundant systems.
x Power supply predictive failure occurs.
x Power supply redundancy is lost. This does not apply to
nonredundant systems.
x Correctable errors occur over a threshold of 10 and migrate to a
spare DIMM (memory sparing). This indicates that the user no
longer has spare DIMMs indicating a redundancy lost condition.
Corresponding DIMM LED should light up.

x SMI Lane Failover
Amber ~1 Hz Non-critical Non-fatal alarm – system is likely to fail:
x CATERR is asserted.
x Critical temperature threshold is asserted.
x Critical voltage threshold is asserted.
x Critical fan threshold is asserted.
Amber Solid on
Critical, non-
recoverable
Fatal alarm – system has failed or shutdown:
x CPU is missing.
x Thermtrip is asserted.
x VRD is hot asserted.
x SMI Timeout is asserted.
x Non-recoverable temperature threshold is asserted.
x Non-recoverable voltage threshold is asserted.
x Power fault / Power Control Failure occur.
x Fan redundancy is lost due to insufficient system cooling. This
does not apply to non-redundant systems.
x Power supply redundancy is lost due to insufficient system
power. This does not apply to non-redundant systems.
This state also happens when AC power is first applied to the
system. This indicates that the BMC is booting.
Off N/A Not ready
AC power is off, if non-degraded, non-critical, critical, or non-
recoverable conditions exist.
Note: This is BIOS-Driven functionality through IPMI “Set Fault Indication” command.
