Power down the server
Before powering down the server for any upgrade or maintenance procedures, perform a backup of critical server data and programs.
IMPORTANT: When the server is in standby mode, auxiliary power is still being provided to the system.
To power down the server, use one of the following methods:
●Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server enters standby mode.
●Press and hold the Power On/Standby button for more than 4 seconds to force the server to enter standby mode.
This method forces the server 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 HP iLO.
This method initiates a controlled remote shutdown of applications and the OS before the server enters standby mode.
Before proceeding, verify the server is in standby mode by observing that the system power LED is amber.
