Description

N/A
Not ready
AC power off
Green
Solid on
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 ten and migrating to a
spare DIMM (memory sparing). This indicates that the user no
longer has spare DIMMs indicating a redundancy lost
condition. The 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 the second bullet above.
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 the 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, no good
memory present
Run-time memory uncorrectable error in non-redundant mode
IERR signal asserted
Processor 1 missing
Temperature (e.g., CPU ThermTrip, memory TempHi, critical
threshold crossed)
No power good – power fault
Processor configuration error (e.g., processor stepping
mismatch)

System Identification LED
The blue system identification LED is used to help identify a system for servicing. This is
especially useful when the system is installed in a high density rack or cabinet that is populated
with several similar systems.
The blue System ID LED can be illuminated using one of the following mechanisms:
