v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v If an action step is preceded by "(Trained technician only)", that step must be performed only by a trained
technician.
v Go to the IBM support website at http://www.ibm.com/supportportal to check for technical information, hints,
tips, and new device drivers or to submit a request for information.

No Memory
1. Make sure that there is at least one DIMM installed in the
Detected.
server.
2. If there are no memory fault recorded in the logs and no
DIMM connector error LEDs are lit, make sure that all
DIMM connectors are enabled by using the Setup utility or
the Advance Settings Utility (ASU).
3. Reinstall all DIMMs in the correct population sequence (see
Memory module installation for more information).
4. Replace the processor (see Removing a microprocessor and
heat sink and Installing a microprocessor and heat sink).
5. Replace the system board (see Removing the system board
and Installing the system board).
DIMM PFA Note: Each time you install or remove a DIMM, you must
Threshold disconnect the server from the power source; then, wait 10
Exceeded. 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 (see Memory module installation for
memory population sequence).
3. If the error still occurs on the same DIMM, replace the
affected DIMM (see Removing a memory module and
Memory module installation
4. If the problem occurs on the same DIMM connector, swap
other DIMMs (in the same memory channel) to a different
memory channel or microprocessor (see Memory module
installation for memory population sequence). If the
problem follows a moved DIMM to a different memory
channel, replace the affected DIMM.
5. (Trained technician only) If the problem occurs on the same
DIMM connector, check the DIMM connector. Remove any
foreign material on the DIMM connector, if found. If the
connector is damaged, replace the system board (see
Removing a memory module and Memory module
installation).
6. (Trained technician only) Remove the affected
microprocessor and check the microprocessor socket pins
for any damaged pins. If a damage is found or the
microprocessor is an upgrade part, replace the system
board.
7. (Trained technician only) Replace the affected
microprocessor (see Removing a microprocessor and heat
sink and Installing a microprocessor and heat sink).
8. (Trained technician only) Replace the system board.
