The bi-color System Status LED operates as follows:
Table 40. System Status LED
Color State Criticality Description
Off N/A Not ready AC power off
Green/
Amber
Alternating
Blink
Not ready Pre DC Power On – 20-30 second BMC Initialization when AC is
applied to the server. Control Panel buttons are disabled until BMC
initialization is completed.
Green Solid on System OK System booted and ready.
Green Blink Degraded System degraded
 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 spare DIMMs indicating a redundancy lost condition.
Corresponding DIMM LED should light up.
 In a mirrored configuration, when memory mirroring takes place
and system loses memory redundancy. This is not covered by (2).
 Redundancy loss such as power supply or fan. This does not
apply to non-redundant subsystems.
 PCI Express* 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
Amber Blink Non-critical Non-fatal alarm – system is likely to fail
 Critical voltage threshold crossed
 VRD hot asserted
 Minimum number of fans to cool the system are not present or
have failed
 In a non-sparing and non-mirroring mode, if the threshold of ten
correctable errors is crossed within the window.
Amber Solid on Critical, non-
recoverable
Fatal alarm – system has failed or shut down
 DIMM failure when there is one DIMM present and no good
memory is 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)
