Power on and power off problems
Use this information to resolve issues when powering on or powering off the server.
Embedded hypervisor is not in the boot list
Check Lenovo ServerProven website to validate that the embedded hypervisor device is supported for the server.
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.
Make sure that the embedded hypervisor device is listed in the list of available boot options. From the management controller user interface, click.
For information about accessing the management controller user interface, see:
Accessing the XClarity Controller web interfacesection in the XCC documentation compatible with your server at Lenovo XClarity Controller portal page.
See the documentation that comes with the optional embedded hypervisor flash device to validate that the device is configured correctly.
Check Lenovo Data Center Support for any tech tips (service bulletins) related to the embedded hypervisor and the server.
Make sure that other software works on the server to ensure that it is working properly.
Server does not power on (no indication that input power is connected to the server)
Check the event log for any events related to the server not powering on.
Check for any LEDs that are flashing amber.
Check the power LED on the front operator panel.
Check the front operator panel LCD display for error indications.
- Check the power supply LEDs and ensure that the power supplies are functioning:
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.
Make sure that the power cords are correctly connected to a working electrical outlet. The power source meets the input power requirements for the installed power supplies (see the power supply labels).
Disconnect and reconnect the input power cords.
Reseat the power supplies.
Replace the power supplies one by one, and check the power button function after installing each one.
If the problem still cannot be resolved, please collect the failure information with system logs captured to Lenovo support.
Server does not power off
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:
Turn off the server by pressing the power button and holding it down for 5 seconds.
Restart the server.
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 restart the server.
If the problem remains or if you are using an ACPI-aware operating system, suspect the system board.
