Troubleshooting Using LED Indicators
LED3
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."
The internal temperature of the server has
exceeded the warning or critical level.
