Description
00h
Fully redundant
System has lost one or more fans and is running in non-redundant
mode. There are enough fans to keep the system properly cooled,
but fan speeds will boost.
Fan redundancy loss indicates failure of one or more
fans.
Look for lower (non) critical fan errors, or fan
removal errors in the SEL, to indicate which fan is
causing the problem, and follow the troubleshooting
steps for these event types.
01h
Redundancy lost
02h
Redundancy degraded
03h
Non-redundant, sufficient from redundant
04h
Non-redundant, sufficient from insufficient
05h
Non-redundant, insufficient
System has lost fans and may no longer be able to cool itself
adequately. Overheating may occur if this situation remains for a
longer period of time.
06h
Non-redundant, degraded from fully
redundant
System has lost one or more fans and is running in non-redundant
mode. There are enough fans to keep the system properly cooled,
but fan speeds will boost.
07h
Redundant, degraded from non-redundant
System has lost one or more fans and is running in a degraded
mode, but still is redundant. There are enough fans to keep the
system properly cooled.
