Table 12. POST error messages
POST message
189 An attempt has been made to access the server with invalid passwords. After three incorrect
attempts, the server locks up; that is, the logon data fields are no longer available to the user.
201 An error occurred during the memory controller test. This error can be caused by:
•
•
•
•
Action:
If the problem persists, call for service.
229 An error was detected in the L2 cache of one of the microprocessors.
Action:
If the problem persists, call for service.
289 An error occurred during POST memory tests and a failing DIMM was disabled.
Note:
Action:
If the problem persists, call for service.

IBM® xSeries 150 : User's Reference
Incorrectly installed memory
A failing memory module
A processor-board problem
A system board problem
1. If you just installed memory, verify that the new memory is correct for your
server. Also verify that the memory is installed and seated correctly.
2. If the problem persists, check to see if the system has isolated the problem to a
memory module:
• If the System Error light on the operator information panel is on, check to
see if the MEM LED on the diagnostic LED panel is on. If it is on, check
the DIMM Error LEDs next to the memory sockets. If a DIMM Error LED
is on, run the diagnostic program for the memory.
• If the tests fail, replace the DIMM. If the problem persists after you
replace the DIMM, call for service.
• If the memory tests do not fail, call for service.
3. If no error LED is on, the error logs in the Configuration/Setup Utility program
might provide additional information on the memory error.
1. If you just installed a microprocessor, verify that the microprocessor is installed
and seated correctly.
2. If the problem persists, check to see if the system has isolated the problem to a
microprocessor:
• If the System Error light on the operator information panel is on, check to
see if the CPU LED on the diagnostic LED panel is on. If it is on, check the
Microprocessor Error LEDs next to the microprocessor sockets.
— If a Microprocessor LED is on, run the diagnostic program for the
microprocessor indicated by the LED. (If the Secondary
Microprocessor Error LED is on, run the "Alt CPU" diagnostic
program.) If the tests fail, replace the microprocessor.
— If the microprocessor tests do not fail, call for service.
• If no error LED is on, the error logs in the Configuration/Setup Utility
program might provide additional information on the microprocessor
error.
You can use the server with decreased memory.
1. If you just installed memory, verify that the new memory is correct for your
server. Also verify that the memory is installed and seated correctly. Start the
Configuration/Setup Utility program and select Memory Settings from the
Advanced Setup menu to enable the DIMM.
2. If the problem remains, replace the failing DIMM.
