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.
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 "Turn on the server" on page 32.
Turn 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 press the power button.
• Automatic restart after a power interruption.
• Remote power-on requests sent to the Lenovo XClarity Controller.
For information about powering off the server, see "Turn off the server" on page 32.
