Basic and advanced troubleshooting tables
Use the following troubleshooting tables to determine the symptoms or condition of a suspect server
blade. The state of the front panel LEDs can be viewed locally.
NOTE: Virtual front panel LEDs in the iLO 3 TUI are not the same as the front panel LEDs, see

1. For new server installations, review the installation
procedures.
2. Be sure that that the enclosure power cords are
connected to both the power supplies and to the AC
receptacles.
3. Be sure that that AC power, at the proper AC voltage
levels, is available to the receptacles.
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.
A fatal fault has been detected and logged, attempting
to power on the server.
Server blade does not power on after front panel
power button is momentarily pressed (less than

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.
4. An improper SBL or e-keying error can also cause
power on to fail.
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 (SFW or iLO 3 firmware).
1. Cannot access the iLO 3 MP at this time.
Blade health LED is off and iLO 3 LED is flashing
amber or off.

panel health LED and server power LED states show:
Flashing green or steady green, and steady green,
respectively.
A fatal error has been detected and logged while booting
or running system firmware. Examine the iLO 3 MP logs
