Power on and power off problems

Follow this procedure to resolve issues when powering on or powering off the server.

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 device for setup and configuration information.

  3. Make sure that software that is installed in the device works on another server to ensure that the device works properly.

  4. Check Lenovo ServerProven website to validate that the embedded hypervisor device is supported by the server.

  5. Make sure that the embedded hypervisor device is included in the list of available boot options. To view the list of boot sequences, go to Setup Utility, select Startup > Boot Priority Order.

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

The server does not power on​

Complete the following steps until the problem is solved.

Note
The power button will not function until approximately one to three minutes after the server is connected to ac power.

  1. Remove any optional devices that were installed recently. System power problems caused by addition of a device indicates this device is either incompatible or too much for the power supply to support.

  2. Make sure the power cord is securely connected to the server and to a working electrical outlet. Disconnect and reconnect or replace the server power cord.

  3. Remove and reinstall the power supply. If the problem persists, replace the power supply.

  4. Disconnect and reconnect the front panel cable (see System board components for the location of the connector on the system board). If the problem persists, replace the front panel.

Server powers off unexpectedly​

Complete the following steps until the problem is solved.

  1. Make sure the room temperature does not cause overheating, and no object is blocking the airflow in front and back of the server.

  2. Remove any optional devices that were installed recently. System power problems caused by addition of a device indicates this device is either incompatible or too much for the power supply to support.

  3. Make sure the power cord is securely connected to the server and to a working electrical outlet. Disconnect and reconnect or replace the server power cord.

  4. Reseat the power supply. If the problem persists, replace the power supply.

Server does not power off​

Complete the following steps until the problem is solved.

  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 server by pressing and holding the power button for five seconds.

    3. Power on the server.

    4. If the server fails POST and the power button does not work, disconnect the power cord for 20 seconds; then, reconnect the power cord and power on the server.

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