Chapter 3. Server power, controls, and indicators
This chapter describes how to turn on and turn off the server, and what the controls
and indicators mean.
Turning on the server
After you plug the power cord of your server into the power supply and an electrical
outlet, you can start the server in several ways:
•
You can press the power-control button on the front of the server to start the
server.
•
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 system is off, and the Wake on LAN feature is enabled,
the system can be turned on by a network wake-up frame from the onboard Intel
Ethernet controller.
•
The Integrated System Management Processor can also turn on the server.
