Power on the server

After the server performs a short self-test (power status LED flashes quickly) when connected to input power, it enters a standby state (power status LED flashes once per second).

The server can be turned on (power LED on) in any of the following ways:
  • You can press the power button.

  • The server can respond to remote power-on requests sent to Lenovo XClarity Controller via Lenovo XClarity Essentials OneCLI, IPMItool, or SSH CLI.

    For example, run the following command on Lenovo XClarity Essentials OneCLI to power on your server:

    <kbd className="ph userinput">OneCli.exe ospower turnon --bmc <userid>:<password>@<host></kbd>

    For more information about running the ospower command, see OneCLI ospower command.

If the system UEFI power policy is set to always on, the system will be powered on automatically when an AC source is plugged in.
