service technician.
Beep/symptom FRU/action
4-4-4 (Optional system management
adapter not installed in slot 1 or not
functioning correctly)
1. Verify that the adapter is installed in slot 1.
2. Adapter.
3. System board.
Two short beeps
(Information only, the configuration
has changed)
1. Run Diagnostics.
2. Run the Configuration/Setup Utility program.
Three short beeps
1. Reseat the DIMMs
2. Locate the failing DIMMs:
a. Remove all DIMMs from the server.
b. Beginning with the primary bank of DIMMs, return one bank of DIMMs
to the server at a time, restarting the server each time, until the beep
code error returns.
c. Replace one pair of DIMMs at a time in the failing bank with an
identical pair of known good DIMMs, restarting the server after each
pair, until the beep code error returns.
d. Replace one DIMM at a time in the failing pair with an identical known
good DIMM, restarting the server after each DIMM, to identify the failed
DIMM. If the beep code error remains after you have replaced both
DIMMs, go to step 3.
e. Repeat steps 2b through 2d until you have checked all memory banks.
3. System board
One continuous beep
1. Reseat the following components, one at a time, in the order shown,
restarting the server each time:
v
(Trained service technician only) Microprocessor 1
v
(Trained service technician only) Microprocessor 2 (if installed)
2. (Trained service technician only) Remove microprocessor 2 and its VRM
and restart the server.
v
If no beep code occurs, microprocessor 2 might have failed; replace the
microprocessor.
v If the beep code remains, remove microprocessor 1 and install
microprocessor 2 in the connector for microprocessor 1; then, restart the
server. If no beep code occurs, microprocessor 1 might have failed;
replace the microprocessor.

No-beep symptoms
Note: See “System replaceable units” on page 122 to determine which components should be replaced by a field
service technician.
No-beep symptom FRU/action
No beep and the system
operates correctly.
