CAUTION: The power control button on the device and/or the power switch on 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. You can start the server in several ways: • You can turn on the server by pressing the Power Control button on the front of the server. Note: After you plug the power cord of your server into an electrical outlet, wait 20 seconds before pressing the Power Control button. During this time the system-management processor is initializing and the Power Control button does not respond. • 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. • The Netfinity Advanced System Management Processor can also turn on the server. The server can be turned off as follows: • You can turn off the server by pressing the Power Control button on the front of the server. Pressing the Power Control button starts an orderly shutdown of the operating system, if this feature is supported by your operating system, and places the server in standby mode. Note: After turning off the server, wait at least 5 seconds before pressing the Power Control button to power the server on again. • You can press and hold the Power Control button for more than 4 seconds to cause an immediate shutdown of the server and place the server in standby mode. You can use this feature if the operating system hangs. • You can disconnect the server power cords from the electrical outlets to shut off all power to the server. Note: Wait about 15 seconds after disconnecting the power cords for your system to stop running. Watch for the System Power light on the operator information panel to stop blinking. Reset Button: Press this button to reset the server and run the power-on self-test (POST). 8 Hardware Maintenance Manual: Netfinity 4500R Type 8656
