The BMC log is limited in size. When the log is full, new entries will not overwrite
existing entries; therefore, you must periodically clear the BMC log through the
Configuration/Setup Utility program (the menu choices are described in the
User’s
Guide ). When you are troubleshooting an error, be sure to clear the BMC log so
that you can find current errors more easily.
Entries that are written to the BMC log during the early phase of POST show an
incorrect date and time as the default time stamp; however, the date and time are
corrected as POST continues.
Each BMC log entry is displayed on its own page. To display all the data for an
entry, use the Up Arrow and Down Arrow keys or the Page Up and Page Down
keys. To move from one entry to the next, select
Get Next Entry or Get Previous
Entry .
The log indicates an assertion event when an event has occurred. It indicates a
deassertion event when the event is no longer occurring.
Some of the error codes and messages in the BMC log are abbreviated.
If you view the BMC log through the Web interface of the optional Remote
Supervisor Adapter II SlimLine, the messages can be translated.
IPMI BMC system-event log messages
The following table describes the possible IPMI BMC system-event log messages
and suggested actions to correct the detected problems.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.

See Chapter 3, “Parts listing, System x3755 Type 8877 and 7163,” on page 25 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
