Table 7. System Status Indicator Leds - Intel 5000 Series Datasheet

System BIOS
Note: As indicated in the above table, when two FBDIMMs operate in lock-stepped mode. If one
of the FBDIMMs fails, the BIOS will also light the DIMM fault LED of the companion FBDIMM.
This is because the BIOS cannot isolate failures at the individual FBDIMM level in this mode. In
all cases the BMC will light the LEDs after receiving IPMI messages from the BIOS.
3.3.10.2.4 System Status Indicator LEDs
Intel server boards have a system status indicator LED on the front panel. This indicator LED is
used to indicating many different system errors. The table below shows the policies that are
specific to memory errors.

Criticality
Not ready AC power off
Not ready Pre DC power on – 15-20 second BMC initialization when AC is
applied to the server. Control panel buttons are disabled until BMC
initialization is complete.
System OK System booted and ready.
Degraded System degraded
Non-critical Non-fatal alarm – system is likely to fail
Critical, non- Fatal alarm – system has failed or shutdown
recoverable
Intel order number D38960-004
Description
Unable to use all of the installed memory (more than one DIMM
installed).
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. Corresponding DIMM LED should light up.
In mirrored configuration, when memory mirroring takes place
and system loses memory redundancy.
Redundancy loss such as power-supply or fan. This does not
apply to non-redundant sub-systems.
PCI-e link errors
CPU failure / disabled – if there are two processors and one of
them fails
Fan alarm – Fan failure. Number of operational fans should be
more than minimum number needed to cool the system
Non-critical threshold crossed – Temperature and voltage
Critical voltage threshold crossed
VRD hot asserted
Minimum number of fans to cool the system not present or
failed
In non-sparing and non-mirroring mode if the threshold of ten
correctable errors is crossed within the window
DIMM failure when there is one DIMM present, no good
memory present
Run-time memory uncorrectable error in non-redundant mode
IERR signal asserted
Processor 1 missing
Temperature (CPU ThermTrip, memory TempHi, critical
threshold crossed)
No power good – power fault
Processor configuration error (for instance, processor stepping
mismatch)
