Action
1. Make sure that:
v No error LEDs are lit on the front-panel assembly or on the system board.
v The memory modules are seated correctly.
v You have installed the correct type of memory.
v If you changed the memory, you updated the memory configuration in the
Configuration/Setup Utility program.
v All DIMMs are enabled. The server might have automatically disabled a
DIMM when it detected a problem.
v If a DIMM was disabled by a system-management interrupt (SMI), replace
the DIMM.
2. Check the POST error log for error message 289. If POST error message 289
is in the error log, perform the actions listed in the POST error codes table (see
"POST error codes" on page 127). Otherwise, continue to step 3.
3. Run memory diagnostics (see "Running the diagnostic programs" on page 156).
4. Make sure that there is no memory mismatch when the server contains more
than the minimum memory configuration (one 512 MB DIMM) and that you
have installed the correct number of DIMMs (see the User's Guide on the IBM
System x Documentation CD for information about the supported DIMM
configuration).
5. Reseat the DIMMs.
6. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. DIMMs
