8. Run the diagnostics tests for the hard disk drives. When you start a server and press the key according
to the on-screen instructions, the LXPM is displayed by default. (For more information, see the “Startup”
section in the LXPM documentation compatible with your server at
https://sysmgt.lenovofiles.com/help/
topic/lxpm_frontend/lxpm_product_page.html
.) You can perform hard drive diagnostics from this interface.
From the Diagnostic page, click

Based on those tests:
• If the adapter passes the test but the drives are not recognized, replace the backplane signal cable
and run the tests again.
• Replace the backplane.
• If the adapter fails the test, disconnect the backplane signal cable from the adapter and run the tests
again.
• If the adapter fails the test, replace the adapter.
Displayed system memory less than installed physical memory
Complete the following steps until the problem is resolved:
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 that:
• No error LEDs are lit on the operator information panel.
• No memory module error LEDs are lit on the system board.
• Memory mirrored channel does not account for the discrepancy.
• The memory modules are seated correctly.
• You have installed the correct type of memory module (see
for
requirements).
• After changing or replacing a memory module, memory configuration is updated accordingly in the
Setup Utility.
• All banks of memory are enabled. The server might have automatically disabled a memory bank when
it detected a problem, or a memory bank might have been manually disabled.
• There is no memory mismatch when the server is at the minimum memory configuration.
2. Reseat the DIMMs, and then restart the server.
3. Check the POST error log:
• If a memory module was disabled by a systems-management interrupt (SMI), replace the memory
module.
• If a memory module was disabled by the user or by POST, reseat the memory module; then, run the
Setup Utility and enable the memory module.
4. Run memory diagnostics. When you start a solution and press the key according to the on-screen
instructions, the LXPM interface is displayed by default. (For more information, see the “Startup” section
in the LXPM documentation compatible with your server at
https://sysmgt.lenovofiles.com/help/topic/
lxpm_frontend/lxpm_product_page.html
.) You can perform memory diagnostics from this interface. From
the Diagnostic page, click
Run Diagnostic

Memory test
.
5. Re-enable all memory modules using the Setup Utility, and then restart the server.
6. (Trained technician only) Install the failing memory module into a memory module connector for
processor 2 (if installed) to verify that the problem is not the processor or the memory module connector.
7. (Trained technician only) Replace the system board.
