v
One beep indicates successful completion of POST, with no errors.
v More than one beep indicates that POST detected a problem. Error messages
also are displayed during startup if POST detects a hardware-configuration
problem. See “POST beep codes” and “POST error codes” on page 113 for more
information.
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.
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 or diagnostics LEDs indicate a microprocessor
error, the error might be in the microprocessor or in the microprocessor socket. See
“Microprocessor problems” on page 129 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, RS110 Types 6435, 6436, 6437 and 6438 server,” on page 27 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.
