Turning off the server

Use this information to turn off the server.

When you turn off the server and leave it connected to ac power, the server can respond to requests from the Integrated Management Module 2.1 (IMM2.1), such as a remote request to turn on the server. While the server remains connected to ac power, one or more fans might continue to run. To remove all power from the server, you must disconnect the server from the power source.

Some operating systems require an orderly shutdown before you turn off the server. For information about shutting down the operating system, see your operating-system documentation or help 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.

Power caution

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 turns off automatically.
  • 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.
  • If the operating system stops functioning, you can press and hold the power-control button for more than four seconds to turn off the server.
  • The server can be turned off through Wake on LAN.
    Note
    When you install any PCIe adapter, the power cords must be disconnected from the power source before you remove the PCI riser-card assembly. Otherwise, the Wake on LAN feature might not work.
  • The Integrated Management Module 2.1 (IMM2.1) can turn off the server as an automatic response to a critical system failure.
