Turning on the server
You can turn on the server in any of the following ways:
• If the power cords are connected to a power source, you can press the power-
control button on the front of 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 cords of your server into the electrical outlets, wait
approximately 20 seconds before pressing the power-control button. During
this time, the system-management adapter is initializing; therefore, the power-
control button does not respond.
• If the server is turned on and a power failure occurs, the server will restart
automatically when power is restored.
• If ac power is present and the server is in Standby mode, the server can be turned
on from the Remote Supervisor Adapter user interface.
• When you plug in your server for the first time, Wake on LAN can turn on the
server.
• If your server was previously turned on, it must be properly placed in Standby
mode for the Wake on LAN feature to turn on the server.
Complete the following steps to manually turn on the server:
1. Review the information in “Safety” on page v.
2. Turn on all external devices, such as the monitor.
3. Plug the server power cords into the power source.
4. Press the power-control button on the front of the server.
Note: While the server is powering up, the power-on LED on the front of the
server is lit.
