Power 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.

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.

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 Power on the server.
