Resolving installation issues

Make sure that the power-control button is working correctly:

1. Disconnect the server power cords.

2. Reconnect the power cords.

3. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 1a and 1b.

   • (Trained technician only) If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

   • If the server does not start, bypass the power-control button by using the force power-on jumper. If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

Make sure that the reset button is working correctly:

1. Disconnect the server power cords.

2. Reconnect the power cords.

3. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 2a and 2b.

   • (Trained technician only) If the server starts, replace the operator information panel.

   • If the server does not start, go to step 3.

Make sure that both power supplies installed in the server are of the same type. Mixing different power supplies in the server will cause a system error (the system-error LED on the front panel turns on).

• The power cords are correctly connected to the server and to a working electrical outlet.

• The type of memory that is installed is correct.

• The DIMMs are fully seated.

• The LEDs on the power supply do not indicate a problem.

• The processors are installed in the correct sequence.

Reseat the following components:

1. Operator information panel connector

2. Power supplies

Replace the following components. restarting the server each time:

1. Operator information panel connector

2. Power supplies

If you just installed an optional device, remove it, and restart the server. If the server now starts, you might have installed more devices than the power supply supports.

See Power supply LEDs.

Correct any errors that are indicated by the light path diagnostics LEDs.

Make sure that the server supports all the processors and that the processors match in speed and cache size.

You can view processor details from system setup.

To determine if the processor is supported for the server, see Lenovo ServerProven website.

(Trained technician only) Make sure that processor 1 is seated correctly

(Trained technician only) Remove processor 2 and restart the server.

Replace the following components one at a time, in the order shown, restarting the server each time:

1. (Trained technician only) Processor

2. (Trained technician only) System board

Make sure that the optional embedded hypervisor flash device is selected on the boot manager <F12> Select Boot Device at startup.

Make sure that the embedded hypervisor flash device is seated in the connector correctly.

See the documentation that comes with the optional embedded hypervisor flash device to validate that the device is configured correctly.

Make sure that other software works on the server.

Observe the associated yellow hard disk drive status LED. If the LED is lit, it indicates a drive fault.

If the status LED is lit, remove the drive from the bay, wait 45 seconds, and reinsert the drive, making sure that the drive assembly connects to the hard disk drive backplane.

Observe the associated green hard disk drive activity LED and the yellow status LED and perform corresponding operations in different situations:

Make sure that the hard disk drive backplane is correctly seated. When it is correctly seated, the drive assemblies correctly connect to the backplane without bowing or causing movement of the backplane.

Reseat the backplane power cable and repeat steps 1 through 3.

Reseat the backplane signal cable and repeat steps 1 through 3.

Suspect the backplane signal cable or the backplane:

• Replace the affected backplane signal cable.

• Replace the affected backplane.

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 Lenovo XClarity Provisioning Manager portal page.) You can perform hard drive diagnostics from this interface. From the Diagnostic page, click Run Diagnostic > HDD test/Disk Drive Test.*

• 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 Specifications or DC Persistent Memory Module (DCPMM) setup 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.

• When DCPMMs are installed:

  1. If the memory is set in App Direct or Mixed Memory Mode, all the saved data have been backed up, and created namespaces are deleted before any DCPMM is replaced.

  2. Refer to DC Persistent Memory Module (DCPMM) setup and see if the displayed memory fits the mode description.

  3. If DCPMMs are recently set in Memory Mode, turn it back to App Direct Mode and examine if there is namespace that has not been deleted (see DC Persistent Memory Module (DCPMM) setup).

  4. Go to the Setup Utility, select System Configuration and Boot Management > Intel Optane DCPMMs > Security, and make sure all the DCPMM units are unlocked.

Reseat the memory modules, and then restart the server.

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.

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 Lenovo XClarity Provisioning Manager portal page.) You can perform memory diagnostics with this interface. From the Diagnostic page, go to Run Diagnostic > Memory test or DCPMM test.

Re-enable all memory modules using the Setup utility, and then restart the server.

(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.

(Trained technician only) Replace the system board.
