POST message				Description
186	A system board or hardware error occurred.
	Action:		Call for service.
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, 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.
