Turning on the server

© Copyright IBM Corp. 2000
This chapter describes how to start the server, and what the controls and indicators
mean.
Turning on the server refers to the act of plugging the power cord of your server into
the power source and starting the operating system.
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.
— The Wake on LAN feature is enabled in the Configuration/Setup Utility
program.
— The Wake on LAN adapter is installed in PCI slot 1 and is connected to the
system board with the 3-pin auxiliary power connector.
Note: For more detailed information about these features, refer to the User's
Reference on the IBM xSeries Documentation CD.
• If the optional system-management adapter is installed in the server, the system-
management adapter can turn on the server.
