Power down the node

About this task
CAUTION:
Before powering down the node, perform a backup of critical server data and programs. Removing the
node while the Do not remove LED is on may result in data loss or corruption. The node can be safely
removed from the chassis only after the Do not remove LED is off.
IMPORTANT:
When the node is in standby mode, auxiliary power is still being provided to the system.
To power down the node , 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 node enters standby
mode.
• Press and hold the Power On/Standby button for more than 4 seconds to force the node to enter standby
mode.
This method forces the node 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 node enters
standby mode.
Before proceeding, verify that the node is in standby mode by observing that the system power LED is amber.
