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
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.
See the documentation that comes with the optional embedded hypervisor flash device for setup and configuration information.
Check Lenovo ServerProven website to validate that the embedded hypervisor device is supported for the server.
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
Opening and Using the XClarity Controller Web Interfacesection in the XCC documentation compatible with your server at:
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
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 system board.
- Reseat the power supply.
Replace the power supply.
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.
