Post Beep Codes - IBM 436854u - System x3200 M2 5U Mini Tower Server Problem Determination And Service Manual

POST beep codes

A beep code is a combination of short or long beeps or series of short beeps that
are separated by pauses. For example, a "1-2-3" beep code is one short beep, a
pause, two short beeps, and pause, and three short beeps. A beep code indicates
that POST has detected a problem.
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 multiple error codes indicate a microprocessor error, the error might
be in a microprocessor or in a microprocessor socket. See "Microprocessor
problems" on page 145 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, System x3200 M2 Types 4367 and 4368," on page 33 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.
