v
Start the blade server automatically when power is restored after a power failure.
If a power failure occurs, the BladeCenter unit and then the blade server can start automatically when
power is restored. You must configure the blade server to restart through the management module.
v
Start the blade server remotely using the management module.
After you initiate the power-on process, the power-on LED blinks slowly for about 15 seconds, then is
lit solidly when the power-on process is complete.
Turning off the blade server
When you turn off the blade server, it is still connected to power through the BladeCenter unit. 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 unit.
Shut down the operating system before you turn off the blade server. See the operating-system
documentation for information about shutting down the operating system.
You can turn off the blade server in one of the following ways.
v
Turn off the blade server by pressing the power-control button for at least 5 seconds.
The power-control button is on the blade server behind the control panel door. See “Blade server
control panel buttons and LEDs” on page 6 for the location.
Note:
The power-control LED can remain on solidly for up to 1 minute after you push the
power-control button. After you turn off the blade server, wait until the power-control LED is blinking
slowly before you press the power-control button to turn on the blade server again.
If the operating system stops functioning, press and hold the power-control button for more than 5
seconds to force the blade server to turn off.
v
Use the management module to turn off the blade server.
The power-control LED can remain on solidly for up to 1 minute after you initiate the power-off
process. After you turn off the blade server, wait until the power-control LED is blinking slowly before
you initiate the power-on process from the AMM to turn on the blade server again.
Use the management-module Web interface to configure the management module to turn off the blade
server if the system is not operating correctly.
For additional information, see the online documentation or the
User's Guide
for the management
module.
