Resolving installation issues

See this topic to learn how to resolve issues that you might have when setting up your system.

Use the information in this section to diagnose and resolve problems that you might encounter during the initial installation and setup of your server.

Server does not power on​

Note
The power-control button will not function until approximately 5 to 10 seconds after the server has been connected to power.
  1. If an extra optional device has been just installed, remove it and power on the server again. If the server is powered on this time, it indicates adding this optional device takes more than the system power could afford.
  2. Check the power button LED:
    • If the power button LED is lit, check the system event log.
      • If there is readable system event log without uefi errors, replace the system board (see System board replacement (trained technician only)).
      • In the following cases, call Lenovo Service.
        • There is readable system event log with uefi errors.
        • There is no readable system event log.
    • If the power button LED is not lit:
      1. Disconnect and reconnect the power cable.
      2. Make sure the power supplies are of the same type (the system-error LED would be lit if power supply units do not match), and reseat all the units.
      3. Check if any power supply error LED it lit (see Power supply LEDs), and replace the faulty unit if any is found.
      If the problem persists, call Lenovo service.
The following steps are for Lenovo Service only.
  1. If there is readable system event log with uefi errors, replace the Root of Trust Module (see Firmware and Root of Trust/TPM 2.0 Security Module replacement (trained technician only)).
  2. If there is no readable system event log, but the power button LED is still lit, bring the following replacement units, run diagnostic isolation, and replace the faulty parts.
  3. If the power button LED is not lit, bring the following replacement units, run diagnostic isolation, and replace the faulty parts.

The server immediately displays the POST Event Viewer when it is turned on​

Complete the following procedure to solve the problem.

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

  2. 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 ServerProven.

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

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

  5. 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

Embedded hypervisor is not in the boot list​

Complete the following steps until the problem is resolved:

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

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

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

  4. Make sure that other software works on the server.

Displayed system memory is less than installed physical memory​

Complete the following procedure to solve the problem.

Note
Each time you install or remove a memory module, 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 PMEM rules 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.

    • If PMEMs are installed:

      1. Refer to PMEM rules and see if the displayed memory fits the mode description.

      2. All the saved data have been backed up, and created namespaces are deleted before any PMEM is replaced or added.

      3. Go to the Setup Utility, select System Configuration and Boot Management > Intel Optane PMEMs > Security, and make sure security of all the PMEM units is disabled.

  2. Reseat the memory modules, 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 specified in the on-screen instructions, the Lenovo XClarity Provisioning Manager interface is displayed by default. You can perform memory diagnostics with this interface. From the Diagnostic page, go to Run Diagnostic > Memory test or PMEM test.

    Note
    When PMEMs are installed, run diagnostics based on the mode that is set presently:

    • App Direct Mode:

      • Run Memory Test for DRAM memory modules.

      • Run PMEM Test for PMEMs.

  5. Reverse the modules between the channels (of the same processor), and then restart the server. If the problem is related to a memory module, replace the failing memory module.

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

  7. (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.

  8. (Trained technician only) Replace the system board.

A Lenovo optional device that was just installed does not work.​

  1. Make sure that:

    • The device is supported for the server (see ServerProven).

    • You followed the installation instructions that came with the device and the device is installed correctly.

    • You have not loosened any other installed devices or cables.

    • You updated the configuration information in system setup. When you start a server and press F1 to display the system setup interface. Whenever memory or any other device is changed, you must update the configuration.

  2. Reseat the device that you just installed.

  3. Replace the device that you just installed.

Voltage planar fault is displayed in the event log​

Complete the following procedure to solve the problem.

  1. Revert the system to the minimum configuration. See Specifications for the minimally required number of processors and DIMMs.

  2. Restart the system.

    • If the system restarts, add each of the items that you removed one at a time, restarting the system each time, until the error occurs. Replace the item for which the error occurs.

    • If the system does not restart, suspect the system board.
