This method forces the server blades or workstation blades to enter standby mode without properly
exiting applications and the OS. It provides an emergency shutdown method if an application stops
responding.
• Execute one of the following commands using the Onboard Administrator CLI:
poweroff server [bay number]
or
poweroff server [bay number] force
The first command initiates a controlled shutdown of applications and the OS before the server blades
or workstation blades enters standby mode. The second form of the command forces the server blades
or workstation blades to enter standby mode without exiting applications and the OS. This emergency
method forces a shutdown if an application stops responding.

Power down the storage blade
In systems that use storage blade as external data storage, be sure that the partner server blades or
workstation blades are the first to be powered down and the last to be powered back up. Taking this
precaution enables the system to initialize the storage blade when they are powered up and to shut down the
storage blade and the OS in an orderly manner when they are powered down.
IMPORTANT: If installing a hot-plug device, it is not necessary to power down the storage blade.
