select System Information, then select Product Data.If the problem persists, call for
service.
188 A vital product data (VPD) error occurred.
Action: Call for service.
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:
• Incorrectly installed memory
• A failing memory module
• A system board problem
Action: 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, call for service.
229 An error was detected in the L2 cache of one of the microprocessors.
Action: 1. If you just installed a microprocessor, verify that the microprocessor is installed
and seated correctly.
2. If the problem persists, call for service.
289 An error occurred during POST memory tests, and a failing DIMM was disabled.
Note: You can use the server with decreased memory.
Action: 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.
If the problem persists, call for service.
301 303 An error occurred during the keyboard and keyboard controller test. These error messages also
might be accompanied by continuous beeping.
Action: Ensure that:
1. Nothing is resting on the keyboard and pressing a key.
2. No key is stuck.
3. The keyboard cable is connected correctly to the keyboard and to the correct
connector on the server.
Running the diagnostic tests can isolate the server component that failed, but you must have your
system serviced. If the error message remains, call for service.
Note: If you just connected a new mouse or other pointing device, turn off the server and
disconnect that device. Wait at least 5 seconds; then, turn on the server. If the error
message goes away, replace the device.
