Chapter 2. Power, controls, and indicators
Use this information to view power features, turn on and turn off the blade server, and view the functions of
the controls and indicators.
Turning on the blade server
After you connect the blade server to power through the BladeCenter chassis, the blade server can be
started in any of the following ways.
• You can press the power button on the front of the blade server (see "Blade server controls and LEDs" on
page 16) to start the blade server. The power button works only if local power control is enabled for the
blade server. Local power control is enabled and disabled through the advanced management module
web interface.
Notes:
1. Wait until the power LED on the blade server flashes slowly before you press the power button. While
the service processor in the blade server is initializing and synchronizing with the advanced
management module, the power-on LED flashes rapidly, and the power-control button on the blade
server does not respond. This process can take approximately 90 seconds after the blade server has
been installed.
2. While the blade server is starting, the power LED on the front of the blade server is lit and does not
flash. See "Blade server controls and LEDs" on page 16 for the power LED states.
• If a power failure occurs, the BladeCenter chassis and the blade server can be configured through the
advanced management module web interface to start automatically when power is restored.
• You can turn on the blade server through the advanced management module web interface. For more
information about the advanced management module web interface, see the IBM BladeCenter Advanced
Management Module: User's Guide.
• You can turn on the blade server through the Wake on LAN feature. The blade server must be connected
to power (the power-on LED is flashing slowly), the blade server must be communicating with the
advanced management module, the operating system must support the Wake on LAN feature, and the
Wake on LAN feature must be enabled through the advanced management module interface.
Note: Procedure to enable the Wake on LAN feature varies depending on the network device. Refer to the
documentation that is provided for your network device for more information.
Turning off the blade server
When you turn off the blade server, it is still connected to power through the BladeCenter chassis. The blade
server can respond to requests from the service processor, such as a remote request to turn on the blade
server. To remove all power from the blade server, you must remove it from the BladeCenter chassis.
Before you turn off the blade server, shut down the operating system. See the operating-system
documentation for information about shutting down the operating system.
The blade server can be turned off in any of the following ways:
• You can press the power button on the blade server (see "Blade server controls and LEDs" on page 16).
Pressing the button starts an orderly shutdown of the operating system, if this feature is supported by the
operating system.
