Power off the server
The server remains in a standby state when it is connected to a power source, allowing the BMC 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):
ThinkSystem System Manager can place the server in a standby state as an automatic response to a critical system failure.

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 BMC. For information about powering on the server, see Lenovo ThinkSystem System Manager User Guide.
