IBM 206 manual Server power features, Turning on the server

Server power features

When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic is shut down; however, the server can respond to remote requests to turn on the server. The power-on LED flashes to indicate that the server is connected to an ac power source but is not turned on (standby mode).

Turning on the server

Approximately 20 seconds after the server is connected to ac power, the power-control button becomes active, and you can turn on the server and start the operating system by pressing the power-control button.

The server can also be turned on in any of the following ways:

vIf a power failure occurs while the server is turned on, the server will restart automatically when power is restored.

vIf your operating system supports the system-management software for an optional Remote Supervisor Adapter II, the system-management software can turn on the server.

vIf your operating system supports the Wake on LAN feature, the Wake on LAN feature can turn on the server.

vIf an optional Remote Supervisor Adapter II is installed in the server, the server can be turned on from the Remote Supervisor Adapter II user interface.

Note: 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.
