If POST detects a problem, more than one beep might sound, or an error message
is displayed. See “Beep code descriptions” and “Dynamic System Analysis
diagnostic programs and messages” on page 108 for more information.
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 71.
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 or beep code. When
this occurs, correct the cause of the first error message or beep code. The other
error messages and beep codes usually will not occur the next time POST runs.
Exception: If multiple error codes or light path diagnostics LEDs indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor
socket. See “Microprocessor problems” on page 93 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 7901 and 7902,” on page 19 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.
