187 The VPD serial number is not set.
Action: The system serial number is set in the VPD EEPROM at the time
of manufacturing. If the system board has been replaced, the
system serial number will be invalid and should be set. From the
main menu of the Configuration/Setup Utility program, select
System Information , and then select Product Data. If the
problem remains, 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.
Action: Call for service.
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
• A memory-board problem
Action: 1. If you just installed memory, verify that the new memory is
correct for the server. Also verify that the memory is installed
and seated correctly.
2. If the problem remains, 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 the diagnostic panel to see if the
MEM LED on the diagnostic LED panel is on. See
“Level 2 diagnostic panel LEDs” on page 124 to identify
the diagnostic panel and locate the LED. If it is on,
check the DIMM error lights next to the memory sockets.
If a DIMM error LED is on, run the diagnostic program
for the memory.
Note: If the server had a DIMM failure, an LED on the
memory board indicates the failing DIMM. If the
LED is not visible with the memory board in its
connector, you can remove the memory board
and press the button on the board to light the
LED for the failing DIMM.
• If the tests fail, replace the DIMM. If the problem
remains 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.
If the problem remains, call for service.
