Power off the system

The system 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 system (power status LED off), all power cables must be disconnected.

Depending on the node configuration, the front operator panel with the power button and LED can be one of the following.

The Lenovo XClarity Controller can place the system in a standby state as an automatic response to a critical system failure.

When in a standby state, the solution can respond to remote power-on requests sent to the Lenovo XClarity Controller. For information about powering on the solution, see Power on the system.
