conditions, remove the server from the rack.
•
Remove the PCI riser cages (on page 31 ).
•
Remove the air baffle (on page 32 ).

Remove the security bezel (optional)
To access the front panel components, unlock and then remove the security bezel. The security bezel is only

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 iLO 4.
This method initiates a controlled remote shutdown of applications and the OS before the server enters
standby mode.
