Description
 BMC booting Linux*. (Indicated by Chassis ID solid ON). System in
degraded state (no manageability). Control has been passed from
BMC uBoot to BMC Linux* itself. It will be in this state for ~10-~20
seconds.
 BMC Watchdog has reset the BMC.
 Power Unit sensor offset for configuration error is asserted.
 HDD HSC is off-line or degraded.
Amber
~1 Hz blink
Non-critical -
System is
operating in a
degraded state
with an impending
failure warning,
although still
functioning
Non-fatal alarm – system is likely to fail:
 Critical threshold crossed – Voltage, temperature (including HSBP
temp), input power to power supply, output current for main power
rail from power supply and PROCHOT (Therm Ctrl) sensors.
 VRD Hot asserted.
 Minimum number of fans to cool the system not present or failed
 Hard drive fault
 Power Unit Redundancy sensor – Insufficient resources offset
(indicates not enough power supplies present)
 In non-sparing and non-mirroring mode if the threshold of
correctable errors is crossed within the window
 Correctable memory error threshold has been reached for a failing
DDR3 DIMM when the system is operating in a non-redundant
mode
Amber
Solid on
Critical, non-
recoverable –
System is halted
Fatal alarm – system has failed or shutdown:
 CPU CATERR signal asserted
 MSID mismatch detected (CATERR also asserts for this case).
 CPU 1 is missing
 CPU Thermal Trip
 No power good – power fault
 DIMM failure when there is only 1 DIMM present and hence no
good memory present.
 Runtime memory uncorrectable error in non-redundant mode.
 DIMM Thermal Trip or equivalent
 SSB Thermal Trip or equivalent
 CPU ERR2 signal asserted
 BMC\Video memory test failed. (Chassis ID shows blue/solid-on for
this condition)
 Both uBoot BMC FW images are bad. (Chassis ID shows
blue/solid-on for this condition)
 240VA fault
 Fatal Error in processor initialization:
 Processor family not identical
 Processor model not identical
 Processor core/thread counts not identical
 Processor cache size not identical
 Unable to synchronize processor frequency
 Unable to synchronize QPI link frequency
10.3 BMC Boot/Reset Status LED Indicators
During the BMC boot or BMC reset process, the System Status LED and System ID LED are
used to indicate BMC boot process transitions and states. A BMC boot will occur when AC
power is first applied to the system. A BMC reset will occur after:
