Information LED panel:
The lights on this panel give status information for your
server. See “Information LED panel” on page 9.
Turning on the server
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.
Statement 5
CAUTION:
The power control button on the device and the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one
power cord. To remove all electrical current from the device, ensure that all power cords
are disconnected from the power source.
