Turning on the server

Use this information to turn on the server.

Approximately 5 seconds after the server is connected to ac power, one or more fans might start running to provide cooling while the server is connected to power and the power-on button LED will blink quickly. Approximately 1 to 3 minutes after the server is connected to ac power, the power-control button becomes active (the power-on LED will blink slowly), and one or more fans might start running to provide cooling while the server is connected to power. You can turn on the server by pressing the power-control button.

The server can also be turned on in any of the following ways:
  • If a power failure occurs while the server is turned on, the server will restart automatically when power is restored.
  • If your operating system supports the Wake on LAN feature, the Wake on LAN feature can turn on the server.
Note
  1. When 4 GB or more of memory (physical or logical) is installed, some memory is reserved for various system resources and is unavailable to the operating system. The amount of memory that is reserved for system resources depends on the operating system, the configuration of the server, and the configured PCI options.
  2. Ethernet 1 connector supports Wake on LAN feature.
  3. When you turn on the server with external graphical adapters installed, the Lenovo logo displays on the screen after approximately 3 minutes. This is normal operation while the system loads.
  4. Make sure the left-side cover is closed.
