IBM 7163, Problem Determination And Service Manual

Page: 156 / 210

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/BIOS or the service processor).
Note: The BMC log, which you can view through the Configuration/Setup Utility
program, also contains many information, error, and warning messages.
In the following example, the system-error log message indicates that the server
was turned on at the recorded time.

The following table describes the possible system-error 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.
v 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.

1. Reseat the following components:
a. Microprocessor/memory card. See “Removing a
microprocessor/memory card” on page 51 and “Replacing a
microprocessor/memory card” on page 51.
b. Power supply
2. Replace the following components one at a time, in the order
shown, restarting the server each time:
a. Microprocessor/memory card. See “Removing a
microprocessor/memory card” on page 51 and “Replacing a
microprocessor/memory card” on page 51.
b. Power supply
c. (Trained service technician only) I/O board. See “Removing
the I/O board assembly” on page 68 and “Replacing the I/O
board assembly” on page 69.
Note: This power unit supplies power to the I/O board and the
SAS backplane.
