v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See the parts listing in the Problem Determination and Service Guide to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Error code Description
303 Keyboard controller error.
00019xxx Microprocessor x is not
functioning or failed the
built-in self-test; check VRM
and processor LEDs.
00180xxx A PCI adapter has requested
memory resources that are
not available.
012980xx No update data for
microprocessor x
012981xx
I9990305 An operating system was not
found.
Action
1. Reseat the following components:
a. I/O board
b. Keyboard connection
2. Replace the components listed in step 1 one at a time, in the
order shown, restarting the server each time.
Make sure that microprocessor x is installed correctly. If the
problem remains, replace microprocessor x.
1. Reseat the following components:
a. (Trained service technician only) Microprocessor x
b. Microprocessor tray
2. Replace the components listed in step 1 one at a time, in the
order shown, restarting the server each time.
If a microprocessor or the microprocessor tray must be
replaced, call for service.
1. Change the order of the adapters in the PCI slots. Make sure
that the boot device is positioned early in the scan order.
2. Make sure that the settings for the PCI adapter and all other
adapters in the Configuration/Setup Utility program are correct.
If the memory resource settings are not correct, change them.
3. If all memory resources are being used, remove an adapter to
make memory available to the PCI adapter. Disabling the
BIOS on the adapter should correct the error. See the
documentation that comes with the adapter.
1. Make sure that all microprocessors have the same cache size.
2. Update the BIOS code again.
3. (Trained service technician only) Reseat microprocessor x
4. (Trained service technician only) Replace microprocessor x
1. Make sure that a bootable operating system is installed.
2. Run the diagnostic programs.
3. Reseat the following components:
a. Hard disk drive
b. SAS backplane
c. Cable
d. I/O board
4. Replace the components listed in step 3 one at a time, in the
