Turning off the server When you turn off the server and leave it connected to ac power, the server can respond to remote requests to turn on the server. While the server remains connected to ac power, one or more fans (some models) 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. Statement 5: CAUTION: The power control button on the device and the power switch on the power supply 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. 2 1 The server can be turned off in any of the following ways: v 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 be turned off automatically. v You can press the power-control button to start an orderly shutdown of the operating system and turn off the server, if your operating system supports this feature. v If the operating system stops functioning, you can press and hold the power-control button for more than 4 seconds to turn off the server. v If an optional Remote Supervisor Adapter II SlimLine is installed in the server, the server can be turned off from the Remote Supervisor Adapter II SlimLine user interface. v The server can turn itself off as an automatic response to a critical system failure. 16 System x3400 Types 7973, 7974, 7975, and 7976: User's Guide
