Validate server setup

After powering up the server, make sure that the LEDs are lit and that they are green.

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-on LED off),
you must disconnect all power cables.
To place the server in a standby state (power-on 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-on 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" on page 108.
