POST beep codes
A beep code is a combination of short or long beeps or a 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, a pause, and three short beeps. A beep code other than
one beep indicates that POST has detected a problem. To determine the meaning
of a beep code, see “Beep code descriptions.” If no beep code sounds, see
“No-beep symptoms” on page 56.
Beep code descriptions
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 or light path diagnostics LEDs that
indicate a microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 84 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, Types 1885 and 8853,” on page 15 to determine which components are CRUs
and which components are FRUs.
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
