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 x3550 M3 Types 4254 and 7944,” on page 159 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.
v Go to the IBM support Web site at http://www.ibm.com/systems/support/ to check for technical

Error code Description Action
0058001 PFA threshold exceeded
1. Update the server firmware to the latest level (see
“Updating the firmware” on page 255).
2. Reseat the DIMMs and run the memory test (see
“Running the diagnostic programs” on page 116).
3. Replace the failing DIMM, which is indicated by a
lit LED on the system board.
0058007 DIMM population is unsupported.
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.
0058008 DIMM failed memory test.
1. Update the server firmware to the latest level (see
“Updating the firmware” on page 255).
2. Reseat the DIMMs, and then restart the server.
3. Reverse the DIMMs between the channels (of the
same microprocessor), and then restart the
server. If the problem is related to a DIMM,
replace the failing DIMM.
4. (Trained service technician only) Install the failed
DIMM into a DIMM connector for microprocessor
2 (if installed) to verify that the problem is not the
microprocessor or the DIMM connector.
5. (Trained service technician only) Replace the
system board.
0058015 Start to activate spare memory channel Information only. A failed DIMM has been detected to
activate the memory online-spare feature. Check the
event log for uncorrected DIMM failure events.
00580A1 Invalid DIMM population for mirroring mode
1. If a fault LED is lit, resolve the failure.
2. Install the DIMMs in the correct sequence (see
“Installing a memory module” on page 195).
00580A4 Memory population changed. Information only. Memory has been added, moved, or
changed.
