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. This is not
covered by (2).
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
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 not present
or failed

ten correctable errors is crossed within the window
Amber

Critical, non-

Fatal alarm – system has failed or shutdown
DIMM failure when there is one DIMM present, no good
memory present
