Power on nodes
When a tray is plugged into the enclosure, each node performs a short self-test (power LED flashes quickly - 4 times per second). Once the self test is completed successfully, the node enters a standby state (power LED flashes slowly - once per a second).
You can press the power button.
The node can restart automatically after a power interruption.
The node can respond to remote power-on requests sent to the Lenovo XClarity Controller.
