Server blade preparation
To service any internal server blade component, power down the server blade and remove it from the enclosure.
Power up the server blade
The OA 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 LED 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.
For more information about the OA, see the OA setup and installation guide on the Hewlett Packard Enterprise website.
Power down the server blade
Procedure
•
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 OA CLI to execute one of the following commands:
◦
poweroff server [bay number]
This command initiates a controlled shutdown of applications and the OS before the server blade enters standby
mode.
◦
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.
•
Use the OA GUI to initiate a shutdown:
These symbols, on power supplies or systems, indicate that the equipment is supplied by multiple
sources of power.
WARNING: To reduce the risk of injury from electric shock, remove all power cords to disconnect
power from the system completely.
