20 seconds before pressing the Power Control button. During this time the
system-management processor is initializing and the Power Control

If the server is turned on, a power failure occurs, and unattended- start mode is
enabled in the Configuration/Setup utility program, the server will start
automatically when power is restored.
If AC power is present, the server is off, and the wake-up feature is enabled in the
Configuration/Setup utility program, the wake-up feature will turn on the server
at the set time.
