Server blade power states
The server blade has three power states: standby power, full power, and off. Install the server
blade into the enclosure to achieve the standby power state. Server blades are set to power on
to standby power when installed in a server blade enclosure. Verify the power state by viewing
the LEDs on the front panel, and using
Table 1-3
.
For more front panel LED information, see
“Front panel LEDs” (page 12)

Powering on the server blade
Use one of the following methods to power up the server blade:
NOTE:
To power on blades in a conjoined configuration, only power on the monarch blade.
•
Use a virtual power button selection through iLO.
•
Press and release the monarch power button.
When the server blade goes from the standby mode to the full power mode, the blade power
LED changes from amber to green.
For more information about iLO, see
“Using iLO” (page 41)
.
Powering off the server blade
Before powering down the server blade for any upgrade or maintenance procedures, perform a
backup of critical server data and programs.
Use one of the following methods to power down the server blade:
NOTE:
To power off blades in a conjoined configuration, only power off the monarch blade.
•
Use a virtual power button selection through iLO (Power Management, Power & Reset).
This method initiates a controlled remote shutdown of applications and the OS before the
server blade enter standby mode.
•
Press and release the monarch power button.
This method initiates a controlled shutdown of applications and the OS before the server
blade enter standby mode.
•
Press and hold the monarch power 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. It provides an emergency shutdown method in the event of a hung
application.
Using iLO
The iLO subsystem is a standard component of selected server blades that provides blade health
and remote server manageability. The iLO subsystem includes an intelligent microprocessor,
secure memory, and a dedicated network interface. This design makes iLO independent of the
