Table 1. Power actions and descriptions.

Two column table containing descriptions of the server power and restart actions.

Power Action	Description
Power on server immediately	Select this action item to power on the server and boot the operating system.
Power on server at specified date and time	Select this action item to schedule the server to automatically power on at a specific date and time.
Power off server immediately	Select this action item to power off the server without shutting down the operating system.
Shut down operating system and then power off server 1	Select this action item to shut down the operating system and power off the server.
Shut down operating system and then restart server 1	Select this action item to reboot the operating system.
Restart the server immediately	Select this action item to power cycle the server immediately without shutting down the operating system.
Restart the server with non-maskable interrupt (NMI)	Select this action item to force an NMI on a hung system. Selection of this action item allows the platform operating system to perform a memory dump that can be used for debug purposes of the system hang condition. The IMM2 firmware uses the auto reboot on the NMI setting from the UEFI F1 in the Setup menu to determine if a reboot after the NMI is needed.
Schedule daily/weekly power and restart actions	Select this action item to schedule daily and weekly power and restart actions for the server.
Enter Sleep Mode	When the platform operating system supports the S3 (Sleep Mode) function and the S3 function is enabled, this action item is displayed. When the operating system is on, select this action item to place the operating system into Sleep Mode.
Exit Sleep Mode	When the platform operating system supports the S3 (Sleep Mode) function and the S3 function is enabled, this action item is displayed. Select this action item to wake up the operating system from the Sleep Mode.
If the operating system is in the screen saver or locked mode when a "Shut Down" request is attempted, the IMM2 might not be able to initiate a normal shutdown. The IMM2 will perform a hard reset or shutdown after the power off delay interval expires while the operating system might still be running.
