Power on and power off problems

See this section to resolve issues when powering on or powering off the solution.

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.

Solution does not power on​

Complete the following steps until the problem is resolved:
Note
The power-control button will not function until approximately 5 to 10 seconds after the solution has been connected to power.

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

    1. Disconnect the solution 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 solution starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

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

  2. Make sure that the reset button is working correctly:

    1. Disconnect the solution 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 solution starts, replace the operator information panel.

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

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

  4. Make sure that:

    • The power cords are correctly connected to the solution 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.

  5. Reseat the following components:

    1. Operator information panel connector

    2. Power supplies

  6. Replace the following components. restarting the solution each time:

    1. Operator information panel connector

    2. Power supplies

  7. If you just installed an optional device, remove it, and restart the solution. If the solution now starts, you might have installed more devices than the power supplies support.

  8. See Power supply LEDs.

  9. If the error recurs, check FFDC logs for more details.

    Note
    To collect FFDC logs, you can perform one of the following actions:

    • Insert a USB storage device to the USB connector on SMM2 and then press the USB port service mode button to collect FFDC logs. See System Management Module 2 (SMM2) for the location of the connector and button.

    • Login to the SMM2 WebGUI and click on the Capture button of FFDC in the Management Module section under Enclosure Rear Overview (see Enclosure Rear Overview).

Solution does not power off​

Complete the following steps until the problem is resolved:

  1. Determine whether you are using an Advanced Configuration and Power Interface (ACPI) or a non-ACPI operating system. If you are using a non-ACPI operating system, complete the following steps:

    1. Press Ctrl+Alt+Delete.

    2. Turn off the solution by pressing the power-control button and holding it down for 5 seconds.

    3. Restart the solution.

    4. If the solution fails POST and the power-control button does not work, disconnect the power cord for 20 seconds; then, reconnect the power cord and restart the solution.

  2. If the problem remains or if you are using an ACPI-aware operating system, suspect the system board.

Unexpected shutdown with LED not lit​

Complete the following steps until the problem is resolved:

  1. Check the Lenovo XClarity Controller event log, and resolve related errors if found any.

  2. Reseat power supply.

  3. If the error recurs, replace power supply.
