BMC Functional Specifications ESB2 BMC Core TPS
Revision 1.0
Intel order number E18291-001
260
Color State System Status 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
Correctable errors over a threshold of 10 and migrating to a
spare DIMM (memory sparing). This indicates that the user no
longer has spared DIMMs, indicating a redundancy lost
condition. The corresponding DIMM LED lights.
1
In mirrored configuration, when memory mirroring takes place
and system loses memory redundancy.
1
PCI Express* correctable link errors.
BMC detected
Redundancy loss such as power-supply or fan. Applies only if
the associated platform sub-system has redundancy
capabilities.
CPU disabled
Fan alarm / Fan failure. The 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 PROCHOT1 (Therm Ctrl) sensors.
Battery failure
The system has lost redundancy due to predictive failure
conditions on power supplies
Amber ~1 Hz blink Non-fatal Non-fatal alarm. The system is likely to fail.
BIOS detected
In non-sparing and non-mirroring mode if the threshold of 10
correctable errors is crossed within the window1
PCI Express* uncorrectable link errors.
BMC detected
Critical threshold crossed – Temperature, and PROCHOT
(Therm Ctrl) sensors.
VRD hot-asserted
Minimum number of fans to cool the system not present or
failed
Amber Solid on Fatal Fatal alarm – system has failed or shutdown.
BIOS detected
DIMM failure when there is one DIMM present, no good
memory present1
Run-time memory uncorrectable error in non-redundant mode1
CPU configuration error (for instance, processor stepping
mismatch).
BMC detected
CPU IERR signal asserted
No CPU present or CPU Configuration Errors
CPU THERMTRIP
No power good – power fault
Power unit redundancy sensor – Insufficient resources offset.
indicates not enough power supplies present.
Off N/A Not ready AC power off
