2 Blade server power, controls, and indicators

This chapter describes the power features, how to turn on and turn off the blade server, and what the
controls and indicators mean.

Turning on the blade server

After you connect the system chassis to AC power, the blade server can start in any of the following
ways:
• You can press the power-control button on the front of the blade server (behind the control panel
door) to start the server.
Notes:
1. After you plug the power cords of your system chassis into the electrical outlets, wait until
the power-on LED on the blade server flashes slowly before pressing the blade server
power-control button. During this time, the service processor in the system chassis
management module is initializing; therefore, the power-control button on the blade does
not respond.
2. While the blade server is powering up, the power-on LED on the front of the server is lit.
See "Blade server controls and LEDs" on page 14 for the power-on LED states.
• If a power failure occurs, the system chassis and then the blade server can start automatically
when power is restored (if the blade server is configured through the chassis management
module to do so).
• You can turn on the blade server remotely by means of the service processor in the chassis
management module.
• If your operating system supports the Wake on LAN feature and the blade server power-on LED
is flashing slowly, the Wake on LAN feature can turn on the blade server under the following
conditions:
— The Wake on LAN feature has not been disabled through the management module Web
interface.
— If the blade server was previously turned on and the operating system was shut down
properly.

Turning off the blade server

When you turn off the blade server, it is still connected to AC power through the system 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 system
chassis.
Shut down your operating system before you turn off the blade server. See your operating system
documentation for information about shutting down the operating system. Improper shutdown of a
blade server will not allow that blade server to be restarted using Wake on LAN.
The blade server can be turned off in any of the following ways:
