Emergency Server Power Down Using the Power Button

This emergency power down task using the Power button is preferred to the other emergency tasks, which use the Oracle ILOM CLI or web interface, because it allows the operating system to gracefully shut down. However, because this task has risks, attempt the graceful power down first.

---

Caution - This task forces the main power off. You might corrupt or lose system data, or lose the server configuration (the resources assigned to it) during an immediate power down.

---

1. Press and quickly release the Power button on the front panel.

   This action causes an orderly shutdown of the operating system, and the server enters the standby power mode.

   If the server did not respond or you need a more immediate shutdown, press and hold the Power button for four seconds, which forces the main power off and enters the standby power mode immediately.

   When the main power is off, the Power/OK LED on the front panel begins flashing, indicating that the server is in standby power mode. See About Server Features and Components.

   Caution - When you press the Power button to enter standby power mode, power is still directed to the service processor remote management subsystem and power supply fans. To completely power off the server, you must disconnect the power cords from the back of the power supplies.

2. Disconnect the power cords from the server.
