Green Blink Degraded System degraded:
1. Unable to use all of the installed memory (more than one DIMM
installed).
2. 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.
3. In a mirrored configuration, when memory mirroring takes place
and system loses memory redundancy. This is not covered by
