Resolving installation issues

Use this information 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​

Complete the following steps until the problem is resolved:

  1. Check the event log for any events related to the server not powering on.

  2. Check for any LEDs that are flashing amber.

  3. Check the power LED on the system board.

  4. Reseat the power adapter.

  5. Replace the power adapter and check the power button function after installing each one.

  6. If the issue cannot be resolved by above actions, please call service to review the issue symptom and see whether the system board replacement is necessary.

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

Complete the following steps until the problem is solved.

  1. Correct any errors that are indicated by the front operator panel and error LEDs.

  2. Make sure that the server supports the processor and that the processor matches 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.

  3. (Trained technician only) Make sure that system board is seated correctly

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

  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 solved.

  1. If the server has been installed, moved, or serviced recently, or if this is the first time the embedded hypervisor is being used, make sure that the device is connected properly and that there is no physical damage to the connectors.

  2. See the documentation that comes with the optional embedded hypervisor flash device for setup and configuration information.

  3. Check Lenovo ServerProven website to validate that the embedded hypervisor device is supported for the server.

  4. Make sure that the embedded hypervisor device is listed in the list of available boot options. From the management controller user interface, click Server Configuration > Boot Options.

    For information about accessing the management controller user interface, see Opening and Using the XClarity Controller Web Interface section in the XCC documentation compatible with your server at:

    Lenovo XClarity Controller portal page

  5. Check Lenovo Data Center Support for any tech tips (service bulletins) related to the embedded hypervisor and the server.

  6. Make sure that other software works on the server to ensure that it is working properly.

Displayed system memory 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 Specifications 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 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 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 .

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

  6. (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 Lenovo ServerProven website).

    • 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 the key according to the on-screen instructions to display the Setup Utility. (For more information, see the “Startup” section in the LXPM documentation compatible with your server at Lenovo XClarity Provisioning Manager portal page.) 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.

  4. Reseat the cable connection and check there is no physical damage to the cable.

  5. If there is any cable damages, then replace the cable.

Voltage planar fault is displayed in the event log​

Complete the following steps until the problem is solved.

  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.
