The following table describes the beep codes and suggested actions to correct the
detected problems.
A single problem might cause more than one error message. When this occurs,
correct the cause of the first error message. The other error messages usually will
not occur the next time POST runs.
Exception: If there are multiple error codes that indicate a microprocessor error,
the error might be in a microprocessor or in a microprocessor socket. See
“Microprocessor problems” on page 30 for information about diagnosing
microprocessor 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, xSeries 100 Type 8486,” on page 49 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.
