Turning off the server

Use this information for details about turning off the server.

When you turn off the server and leave it connected to input power, the server can respond to requests to the service processor (the IMM), such as a remote request to turn on the server. While the server remains connected to input power, one or more fans might continue to run. To remove all power from the server, you must disconnect it from the power source.

Some operating systems require an orderly shutdown before you turn off the server. See your operating-system documentation for information about shutting down the operating system.

CAUTION
The power control button on the device do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.


The server can be turned off in any of the following ways:
  • You can turn off the server from the operating system, if your operating system supports this feature. After an orderly shutdown of the operating system, the server will turn off automatically.
  • You can press the power-on button to start an orderly shutdown of the operating system and turn off the server, if your operating system supports this feature.
  • If the operating system stops functioning, you can press and hold the power-on button for more than 4 seconds to turn off the server.
  • The IMM can turn off the server as an automatic response to a critical system failure.
  • You can turn off the server remotely by issuing a power-off command through the IMM2.
