4. If the power button’s integrated LED on front panel
remains off, then reseat the server blade.
5. As a last resort, replace the server blade. This issue is
fixed when the front panel LED states are as follows: blade
health is steady green.

1. Examine enclosure power supply LEDs. If they are not
steady green, then replace power supply.
2. If the enclosure power supply LED is green, then you
might need an additional power supply to supply sufficient
power to run the blades in the enclosure.
3. Examine the iLO 3 MP subsystem logs for events related
to DC power rails.
This issue is fixed when the front panel LEDs are as
follows: Health is steady green and power is steady
green.
A fatal fault has been detected and logged while booting
or running system firmware.
1. Cannot access the iLO 3 MP at this time.
Blade health LED is off and iLO 3 MP is not
running.

2. Must reseat or replace the server blade. This issue is
fixed when the iLO 3 MP logs can be read and both front
panel health LED and server power LED states show:
Flashing green or steady green, and steady green,
respectively.
A warning or critical failure has been detected and
logged while booting or running system firmware.
Blade health LED is flashing amber or red and

DC power or cooling fans or configuration. This issue is
fixed when both front panel health LED and server power
LED states show: Flashing green or steady green, and

3. As a last resort, replace the server blade. This issue is
fixed when the iLO 3 MP menu appears on the system
console.
Nothing can be logged for this condition.
