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, Types 4255, 7945, and 7949 server," on page 157 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
0058001 PFA threshold exceeded
0058007 DIMM population is unsupported
Action
Note: Each time you install or remove a DIMM, you
must disconnect the server from the power source;
then, wait 10 seconds before restarting the server.
1. Check the IBM support website for an applicable
retain tip or firmware update that applies to this
memory error.
2. Swap the affected DIMMs (as indicated by the
error LEDs on the system board or the event
logs) to a different memory channel or
microprocessor (see "Installing a memory module"
on page 217).
3. If the error still occurs on the same DIMM,
replace the affected DIMM.
4. (Trained service technician only) If the problem
occurs on the same DIMM connector, check the
DIMM connector. If the connector contains any
foreign material or is damaged, replace the
system board (see "Removing the system board"
on page 247 and "Installing the system board" on
page 248).
5. (Trained service technician only) Remove the
affected microprocessor and check the
microprocessor socket pins for any damaged
pins. If a damage is found, replace the system
board (see "Removing the system board" on page
247 and "Installing the system board" on page
248).
6. (Trained Service technician only) Replace the
affected microprocessor (see "Removing a
microprocessor and heat sink" on page 238 and
"Installing a microprocessor and heat sink" on
page 240).
Note: Each time you install or remove a DIMM, you
must disconnect the server from the power source;
then, wait 10 seconds before restarting the server.
1. Reseat the DIMMs and restart the server (see
"Removing a memory module (DIMM)" on page
217 and "Installing a memory module" on page
217).
2. Make sure that the DIMMs are installed in the
proper sequence (see "Installing a memory
module" on page 217).
