The tables are designed to cover troubleshooting symptoms from AC power-on up to booting the
OS, specifically in Steps 1-5. In most cases,
States", identifies the step number where troubleshooting should begin. Alternatively, you can skip
Table 1 1, and start with Step 1 in
the table steps to locate the symptom/condition most descriptive of your current server blade status.
This becomes the first step in your troubleshooting procedure. Where appropriate, an action or
actions prescribed in the Action column of
by a reference to the corresponding subsection of this chapter for further information.
NOTE: In Table 1 1, the Unit Identifier (UID)/Locator LED has not been included, because it is
not used directly for troubleshooting server blades. However, indirectly, it can provide useful system
information (for example when it is blue, this indicates the BMC is working). It also indicates the
server blade which has an error or fault condition by illuminating steady blue on the front of the
server blade in question.

Step Condition
1 Server blade appears "dead" -- no front panel
LEDs are on, and no fans are running. BMC and
iLO 2 MP are running.
2 Server blade does not power on after front
panel power button is momentarily pressed (less
than four seconds). BMC is running, if locator
LED (UID) can be turned on or off through the
system console.

Action
Nothing is logged for this condition.
1. For new server installations, review the installation
procedures.
2. Verify that the enclosure's power cord(s) are connected
to both the power supplies and to the AC receptacle(s).
3. Verify that AC power, at the proper AC voltage levels,
is available to the receptacle(s).
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. The preceding
problem is fixed when the front panel LED states are as
follows: Server health is off and Internal health is steady
amber.
A fatal fault has been detected and logged, attempting to
power on the server.
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
may need an additional power supply to supply sufficient
power to run the blades in the enclosure.
3. Examine the iLO 2 MP subsystem logs for events related
to DC power rails.
Preceding problem is fixed when the front panel LEDs are
as follows: Health is off and power is steady green.
