Examine the iLO 2 MP logs for entries related to
processors, processor power modules (PPMs),
shared memory, and core I/O devices (see “Errors
and Reading Error Logs” (page 118)).
NOTE: Be sure to check the console settings from
the Boot Manager for your OS.
The preceding problem is fixed when OS prompt
appears on the system console.

1. Examine console messages for any EFI errors or warnings about BMC
operation or communications.
2. Examine the BMC heartbeat LED; if it is not flashing green, then replace
the system board CRU (see “Management Subsystem” (page 132)).
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.

clip, pencil, or pen to press the INIT button on the front panel to start a
system initialization. 2. Reboot the OS and escalate. 3. Obtain the system
hardware status dump for root cause analysis. 4. Examine the iLO 2 MP
logs for entries related to processors, processor power modules (PPMs),
shared memory, and core I/O devices (see “Errors and Reading Error
Logs” (page 118) for details).
The preceding problem is fixed when the root cause has been determined.
Front panel LEDs indicate that the server detected a fatal error that it

1. Capture the MCA dump with the EFI command, errdump mca. If the
system can boot the OS, you can capture binary MCA dump files online.
2. Examine the iLO 2 MP logs for entries related to processors, processor
power modules (PPMs), shared memory, and core I/O devices (See
“Errors and Reading Error Logs” (page 118) for more details).
