Power up the server blade
The Onboard Administrator initiates an automatic power-up sequence when the server blade is installed.
If the default setting is changed, use one of the following methods to power up the server blade:
•
Use an iLO 2 virtual power button selection for server A and server B.
•
Press and release the server A and server B Power On/Standby button.
When the server blade goes from the standby mode to the full power mode, the system power LED
changes from amber to green.
For more information about the Onboard Administrator, see the enclosure setup and installation guide
on
the HP website (http://www.hp.com/support).
For more information about iLO 2, see "Integrated Lights-Out 2 technology (on page 42)."
Power down the server blade
Before powering down the server blade for any upgrade or maintenance procedures, perform a backup
of critical server data and programs on each server.
Depending on the Onboard Administrator configuration, use one of the following methods to power down
the server blade:
•
Use the virtual power button selection through iLO 2 for both server A and server B.
This method initiates a controlled remote shutdown of applications and the OS before the server
blade enters standby mode.
•
Press and release the server A and server B Power On/Standby buttons.
This method initiates a controlled shutdown of applications and the OS before the server blade
enters standby mode.
•
Press and hold the server A and server B Power On/Standby buttons for more than 4 seconds to
force the server blade to shut down.
This method forces the server blade to enter standby mode without properly exiting applications and
the OS. It provides an emergency shutdown method in the event of a hung application.
CAUTION:
To prevent damage to the server or the operating system, always power down
both server A and server B before removing the server blade from the enclosure.
IMPORTANT:
When the server blade is in standby mode, auxiliary power is still being
provided. To remove all power from the server blade, remove the server blade from the
enclosure.
After initiating a virtual power down command, be sure that both server A and server B are in standby
mode by observing that the system power LEDs are amber.
