Turn off the server

The server remains in a standby state when it is connected to a power source, allowing the Lenovo XClarity Controller to respond to remote power-on requests. To remove all power from the server (power status LED off), you must disconnect all power cables.

Note
If there is an OCP 3.0 Ethernet adapter installed, when the system is powered off but still plugged in to AC power, system fans will continue to spin at a much lower speed. This is the system design to provide proper cooling for the OCP 3.0 Ethernet adapter.
To place the server in a standby state (power status LED flashes once per second):
Note
The Lenovo XClarity Controller can place the server in a standby state as an automatic response to a critical system failure.

  • Start an orderly shutdown using the operating system (if supported by your operating system).

  • Press the power button to start an orderly shutdown (if supported by your operating system).

  • Press and hold the power button for more than 4 seconds to force a shutdown.

  • Send remote power-off commands to Lenovo XClarity Controller via Lenovo XClarity Essentials OneCLI, IPMItool, or SSH CLI.

When in a standby state, the server can respond to remote power-on requests sent to the Lenovo XClarity Controller. For information about powering on the server, see Turn on the server.
