Diagnostic
code
Message Description Action
I.1800F [I.1800F] A
processor family
mismatch has been
detected for one or
more processor
packages. Processors have
mismatched
Family.
1. Make sure that the microprocessor is on the ServerProven
website at http://www.ibm.com/systems/info/x86servers/
serverproven/compat/us.
2. Verify that matching processors are installed in the correct
processor sockets for the server. Correct any mismatch
issues found.
3. Check the IBM support website for a firmware update and
update the server firmware to the latest level (see Updating
the firmware).
4. (Trained technician only) Remove and replace the affected
microprocessor (error LED is lit) with a supported type (see
Removing a microprocessor and heat sink and Installing a
microprocessor and heat sink).
I.18010 [I.18010] A
processor stepping
mismatch has been
detected for one or
more processor
packages. Processors of
the same model
have
mismatched
Stepping ID.
1.
Make sure that the microprocessor is on the ServerProven
website at http://www.ibm.com/systems/info/x86servers/
serverproven/compat/us.
2.
Verify that matching processors are installed in the correct
processor sockets for the server. Correct any mismatch
issues found.
3. Check the IBM support website for a firmware update and
update the server firmware to the latest level (see Updating
the firmware).
4. (Trained technician only) Remove and replace the affected
microprocessor (error LED is lit) with a supported type (see
Removing a microprocessor and heat sink and Installing a
microprocessor and heat sink).
W.50001 [W.50001] A DIMM
has been disabled
due to an error
detected during
POST. DIMM
Disabled.
Note:
Each time you install or remove a DIMM, you must
disconnect the server from the power source; then, wait 10
seconds before restarting the server.
1. Make sure the DIMM is installed correctly (see Memory
module installation).
2. If the DIMM was disabled because of a memory fault,
follow the suggested actions for that error event.
3. If no memory fault is recorded in the logs and no DIMM
connector error LED is lit, you can re-enable the DIMM
through the Setup utility or the Advanced Settings Utility
(ASU).
