Event logs

Error codes and messages are displayed in POST event log, system-event log, integrated management
module (IMM2) event log, and DSA event log.
• POST event log: This log contains the most recent error codes and messages that were generated during
POST. You can view the contents of the POST event log from the Setup utility (see
utility" on page 89). For more information about POST error codes, see
diagnostic codes" on page
• System-event log: This log contains POST and system management interrupt (SMI) events and all events
that are generated by the baseboard management controller that is embedded in the integrated
management module (IMM). You can view the contents of the system-event log through the Setup utility
and through the Dynamic System Analysis (DSA) program (as IPMI event log).The system-event log is
limited in size. When it is full, new entries will not overwrite existing entries; therefore, you must
periodically clear the system-event log through the Setup utility. When you are troubleshooting an error,
you might have to save and then clear the system-event log to make the most recent events available for
analysis. For more information about the system-event log, see
module II (IMM2) error messages" on page
Messages are listed on the left side of the screen, and details about the selected message are displayed
on the right side of the screen. To move from one entry to the next, use the Up Arrow (↑) and Down Arrow
(↓) keys.
Some IMM sensors cause assertion events to be logged when their setpoints are reached. When a
setpoint condition no longer exists, a corresponding deassertion event is logged. However, not all events
are assertion-type events.
• Integrated management module II (IMM2) event log: This log contains a filtered subset of all IMM,
POST, and system management interrupt (SMI) events. You can view the IMM event log through the IMM

Action
1. If the LED blinks at 1Hz, it is functioning
properly and no action is necessary.
2. If the LED is not blinking, (trained
technician only) replace the system board.
The following steps describe the different
stages of the IMM2 heartbeat sequencing
process.
1. When this LED is blinking fast
(approximately 4Hz), this indicates, that the
IMM2 code is in the loading process.
2. When this LED goes off momentarily, this
indicates that the IMM2 code has loaded
completely.
3. When this LED goes off momentarily and
then starts blinking slowing (approximately
1Hz), this indicates that IMM2 is fully
operational. You can now press the power-
control button to power on the server.
4. If this LED does not blink within 30 seconds
of connecting a power source to the server,
(trained technician only) replace the system
board.
