Lenovo THINKSERVER 3821 - Manual (Page 46)

System-event log
The system-event log contains messages of three types:
Information
Information messages do not require action; they record significant
system-level events, such as when the server is started.
Warning
Warning messages do not require immediate action; they indicate possible
problems, such as when the recommended maximum ambient temperature
is exceeded.
Error Error messages might require action; they indicate system errors, such as
when a fan is not detected.
Each message contains date and time information, and it indicates the source of
the message (POST or the IMM).
Integrated management module error messages
The following table describes the IMM error messages and suggested actions to
correct the detected problems. For more information about IMM, see the IMM
User’s Guide on the Web.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 8, “Parts Listing, TD200x Machine Types 3719, 3821, 3822, and 3823,” on page 237 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.
