Turning on the server

Use this information to turn on the server.

Approximately 5 seconds after the server is connected to input power, one or more fans might start running and the power-on LED flashes quickly. Approximately 10 seconds after the server is connected to input power, the power-on button becomes active. After the power-on button becomes active, the power-on LED flashes slowly. You can turn on the server by pressing the power-on button.

1. Press the power-on button to turn on the server.
2. 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.

What to do next

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. 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.
3. Make sure that the left-side cover is closed.
