Turning on the server
© Copyright IBM Corp. 2001
Use the following procedure to start your server.
1.
Turn on all external devices, such as the monitor.
Note: After you plug the power cord into an outlet, wait 20 seconds before
pressing the power control button. During this time, the power control
button will not respond because the system management microprocessor
is being initialized.
2.
Press the power control button on the front of the server. The power-on light
comes on, and the power-on self-test (POST) begins.
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 Advanced System Management processor 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.
•
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.
•
If AC power is present, the server is off, and ring-signal detect is enabled in the
Configuration/Setup Utility program, you can turn on the server by telephone
input.
•
If your operating system supports the system-management software, the system-
management software can turn on the server.
•
If your operating system supports the Wake on LAN feature, the Wake on LAN
feature will turn on the server at the set time.
Note: For more detailed information about the Wake on LAN feature, refer to the
documentation that comes with the Wake on LAN adapter and cables.
