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.

IBM System x3650 M3 Types 4255, 7945, and 7949: Problem Determination and Service Guide
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. Manually re-enable all affected DIMMs if the
server firmware version is older than UEFI v1.10.
If the server firmware version is UEFI v1.10 or
newer, disconnect and reconnect the server to the
power source and restart the server.
3. 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 for memory population).
4. If the problem is related to a DIMM, replace the
failing DIMM (see "Removing a memory module
(DIMM)" on page 217 and "Installing a memory
module" on page 217).
5. (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).
6. (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).
7. (Trained service technician only) If the problem is
related to microprocessor socket pins, replace the
system board (see "Removing the system board"
on page 247 and "Installing the system board" on
page 248).
8. (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).
Information only. A failed DIMM has been detected to
activate the memory online-spare feature. Check the
event log for uncorrected DIMM failure events.
