If the System LED (on front panel) is in the
attention or fault state and the processor
LED is on, then the processor or voltage
regulator has failed—the processor module
in the specified socket needs to be replaced.
If the thermal LED is in the warning or
critical state and the processor LED is on,
then the processor exceeded the warning or
critical level.
A soldered voltage regulator has failed—the
specified board must be replaced.
A plug-in voltage regulator has
failed—specific VRM must be replaced.
n/a
One or both fans in a fan module have
failed—the module must be replaced.
Fan 2 is in front of the power supplies.
The specified DIMM has failed—the DIMM
must be replaced.
If all the LEDs for a rank (0-7) are lit and
the memory config error LED is lit, then the
DIMMs in the specified rank are
mismatched—replace mismatched DIMM.
One of the power supply or power supply
fans have failed—replace the power supply.
The faulty power supply LED (located on
Power supply) will be lit.
The DIMMs in a rank are mismatched. All
the DIMMs in the specified rank (0-7) will
be lit.
The processors are mismatched—replace
mismatched processor.
A required component(s) is not installed in
the system and thus preventing "power-up."
