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 can press the power button.
The server can restart automatically after a power interruption.
The server can respond to remote power-on requests sent to the Lenovo ThinkSystem System Manager.
For information about powering off the server, see Turn off the server.
