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 a virtual power button selection through iLO.
• Press and release the 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 solid green. The health status LED bar flashes green when the Power On/Standby
Button service is being initialized. For more information about the system power LED status, see "Front
panel LEDs and buttons (on page 7)."
For more information about the Onboard Administrator, see the enclosure setup and installation guide on
the Hewlett Packard Enterprise website
(http://www.hpe.com/support/BladeSystem-Enclosures-docs
).
For more information about iLO, see "HPE iLO (on page 57)."
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.
IMPORTANT: When the server blade is in standby mode, auxiliary power is still being
provided to the system.
Depending on the Onboard Administrator configuration, use one of the following methods to power down
the server blade:
• Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server blade
enters standby mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the server blade to
enter standby mode.
This method forces the server blade to enter standby mode without properly exiting applications and
the OS. If an application stops responding, you can use this method to force a shutdown.
• Use a virtual power button selection through iLO.
This method initiates a controlled remote shutdown of applications and the OS before the server
blade enters standby mode.
• Use the Onboard Administrator CLI to execute one of the following commands:
o poweroff server [bay number]
This command initiates a controlled shutdown of applications and the OS before the server blade
enters standby mode.
o poweroff server [bay number] force
This form of the command forces the server blade to enter standby mode without properly exiting
applications and the OS. If an application stops responding, this method forces a shutdown.
