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 4, "Parts listing, System x3690 X5 Types 7147, 7148, 7149, and 7192," on page 249 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.
Error code Description
0051009 No memory detected.
005100A No usable memory detected.
0058001 PFA threshold exceeded
0058007 DIMM population is unsupported.
Action
1. Make sure that the server contains DIMMs.
2. Reseat the DIMMs.
3. Install DIMMs in the correct sequence (see
"Replacing a memory module" on page 296).
1. Make sure that the server contains DIMMs.
2. Reseat the DIMMs.
3. Install DIMMs in the correct sequence (see
"Replacing a memory module" on page 296).
4. Clear CMOS memory to re-enable all the memory
connectors (see Table 2 on page 21).
1. Check IBM support site for an applicable RETAIN
tip or firmware update that applies to this
memory error.
2. At the next maintenance opportunity, swap the
affected DIMM (as indicated by the light path
LED or event log entry) to a different memory
channel. See "Replacing a memory module" on
page 296 for information on DIMM population
sequence.
3. If the PFA re-occurs (on the same DIMM), replace
the affected DIMM as indicated by the light path
LED or event log entry (check for previous
history of PFA).
4. If the problem remains with the same DIMM
connector, inspect the DIMM connector for debris
or damage. If the DIMM connector is damaged,
(train technician only) replace the system board.
1. Reseat the DIMMs, and then restart the server.
2. Remove the lowest-numbered DIMM pair of
those that are identified, and replace it with an
identical pair of known good DIMMs, then restart
the server.
3. Return the removed DIMMs, one pair at a time,
to their original connectors, restarting the server
after each pair, until a pair fails. Replace the
DIMMs in the failed pair with identical known
good DIMMs, restarting the server after each
DIMM is installed. Replace the failed DIMM.
Repeat this step until you have tested all removed
DIMMs.
4. (Trained service technician only) Replace the
system board.
