Power on the solution

After the solution 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 solution can be turned on (power LED on) in any of the following ways:

  • You can press the power button.

  • The solution can restart automatically after a power interruption.

  • The solution can respond to remote power-on requests sent to the Lenovo XClarity Controller.

For information about powering off the solution, see Power off the solution.

The node power button LED (Green) states are as followed:
  • Off: Power is not present or the power supply, or the LED itself has failed.
  • Flashing rapidly (4 times per second): The node is turned off and is not ready to be turned on. The power button is disabled. This will last approximately 5 to 10 seconds.
  • Flashing slowly (once per second): The node is turned off and is ready to be turned on. You can press the power button to turn on the node.
  • On: The node is turned on.
