Examine the iLO 2 MP logs for entries related to
processors, processor power modules (PPMs),
shared memory, and core I/O devices (see
and Reading Error Logs" (page 119)
details).
The preceding problem is fixed, when all boot
devices are found.
Nothing is logged for this condition (system
health is off, internal health is steady green,
external health is steady green, and power is
steady green). Examine the LED next to each
RAID connector, and replace the RAID HBA (if
this LED is either steady amber or steady red, it
indicates RAID drives are degraded or corrupted,
respectively).
The preceding problem is fixed when all of these
LEDs remain off, after next power on.

operation or communications.
2. Examine the BMC heartbeat LED; if it is not flashing green, then
replace the system board CRU (see
for details).
3. Test the operation of the BMC by toggling the UID locator switch
LED on the front panel -- the blue LED is turned on/off by the BMC,
when this switch is toggled
The preceding problem is fixed when the BMC heartbeat LED is flashing
green, and the SEL resumes logging.
Front panel LEDs indicate that the server power is turned on, and it is
either booting or running the OS (system health is steady green, internal
