SEL overview
The System Event Log (SEL) is a non-volatile repository for event messages. Event
messages contain information about system events and anomalies that occur on
the server, BIOS, and event generators. System sensors can also trigger events
that are logged in the SEL.
Some event messages are the result of normal events, such as a normal server
boot, or possible minor problems such as a disconnected keyboard. Other events
may indicate internal failures such as a component over-temp condition where
thresholds, or ranges of acceptable values have been exceeded. As with other
system events, if at any time a component crosses one of these defined thresholds,
an event message will be generated.
Regardless of the event, the appropriate management controller generates an event
message. Event messages are passed to the Baseboard Management Controller
(BMC). The BMC passes the event message to the SEL where it becomes available
for querying by the SEL Viewer utility.
The SEL Viewer provides an interface for the server administrator to view
information in the SEL. The SEL Viewer is available through the EFI based SEL
Viewer utility which is available in the System Management Utility (SMU) that ships
on the standard platform resource CD. The system administrator can use this
information to monitor the server for warnings and potential critical problems.

8. Check the test log, see "Viewing the test log" on page 38. If an error
was recorded in the test log, go to Chapter 6, "Symptom-to-FRU index",
on page 79.
9. Check for the following responses:
v One beep.
v Readable instructions or the main menu.
002
DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in Chapter 6, "Symptom-to-FRU index", on
page 79.
YES. Run the diagnostic tests. If necessary, see
v "Running system diagnostics" on page 37.
v "Setting test options" on page 38.
v "Interpreting test results" on page 38.
v "Getting help on individual tests" on page 38.
If you receive an error, see Chapter 6, "Symptom-to-FRU index", on
page 79.
If the diagnostic tests were completed successfully and you still suspect a
problem, see "Undetermined problems" on page 88.
