Starting the server
After you plug the power cord of your server into the power supply and an electrical
outlet, the server can start in any of the following ways:
You can press the power-control button on the front of the server to start the
server.
Notes:
1. You can install a circular disk over the power-control button to prevent
accidental manual power-off. This disk, known as the power-control button
shield, comes with your server.
2. After you plug the power cord of your server into an electrical outlet, wait
approximately 20 seconds before pressing the power-control button. During
this time, the system is initializing; therefore, the power-control button does
not respond.
If the server is turned on and a power failure occurs, the server will start
automatically when power is restored.
The Wake on LAN feature will turn on the server at the set time (when a Magic
Packet is received), provided that all of the following conditions are met:
AC power is present.
The server is either off or shut down from an Advanced Configuration and
Power Interface (ACPI) operating system.
