The BMC is unable to change the state ofthis LED. Please see the system BIOS EPS for details on Power Status LED states.3.5.2 System Status LEDNote: The system status LED shows the state for the current, most severe fault. For example, ifthere was a critical fault due to one source and a non-critical fault due to another source, thesystem status LED state would be solid on (the state for the critical fault).The system status / fault LED is a bi-color LED. Green (status) indicates normal (solid-on) ordegraded (blink) operation. Amber (fault) indicates a failure state, and overrides the greenstatus. The system status LED is controlled by the BMC, but includes non-BMC-owned sensorsin fault determination (such as BIOS-owned sensors).The BMC-detected states are included in the LED states. For fault states that are monitored byBMC sensors, the contribution to the LED state follows the associated sensor state, with prioritygiven to the most critical asserted state.When the server is powered down (transitions to the DC-off state or S5), the BMC is still onstandby power and retains the sensor and front panel status LED state established before thepower-down event. If the system status is normal when the system is powered down (the LED isin a solid green state), the system status LED will be off.When AC power is first applied to the system, the status LED will turn solid amber, to indicatethat the BMC is booting. If, upon completing the boot, the BMC does not detect abnormalconditions, the LED will turn off until the system is commanded-on.Revision 1.1Intel ® Confidential 15

System Status LED Indicator StatesColorStateCriticalityGreen Solid on Ok System booted and readyDescriptionGreen ~1 Hz blink Degraded System degraded: Non-critical temperature threshold is asserted.Non-critical voltage threshold is asserted.Non-critical fan threshold is asserted.Fan redundancy is lost; sufficient system cooling is maintained.This does not apply to non-redundant systems.Power supply predictive failure occurs.Power supply redundancy is lost. This does not apply to nonredundantsystems.Correctable errors occur over a threshold of 10 and migrate to aspare DIMM (memory sparing). This indicates that the user nolonger has spare DIMMs indicating a redundancy lost condition.Corresponding DIMM LED should light up. 1Amber ~1 Hz blink Non-critical Non-fatal alarm – system is likely to fail: CATERR is asserted.Amber Solid on Critical, nonrecoverableCritical temperature threshold is asserted.Critical voltage threshold is asserted.Critical fan threshold is asserted.Fatal alarm – system has failed or shutdown: CPU is missing.Thermtrip is asserted.VRD hot is asserted.SMI Timeout is asserted.Non-recoverable temperature threshold is asserted.Non-recoverable voltage threshold is asserted.Power fault / Power Control Failure occur.Fan redundancy is lost due to insufficient system cooling. Thisdoes not apply to non-redundant systems.Power supply redundancy is lost due to insufficient systempower. 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 nonrecoverableconditions exist.Note: This is BIOS-Driven functionality through IPMI “Set Fault Indication” command.3.5.3 Chassis ID LEDThe chassis ID LED provides a visual indication of a system being serviced. The state of thechassis ID LED is affected by the following actions:Toggled by turning the chassis ID button on or off.Controlled by the IPMI Chassis Identify command.- Chassis Identify command can be used to blink or deactivate the Chassis ID LED. Itcannot be used to set the LED in the solid-on state.16Intel ConfidentialRevision 1.1
