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 II (IMM2) can turn off the server as an automatic response to a
critical system failure.
