The
Power Control screen displays.

radio button:
–
Power On System turns on the server (the equivalent of pressing the
power button when the server power is off). This option is disabled if
the system is already powered on.
–
Power Off System turns off the server. This option is disabled if the
system is already powered off.
–
NMI (Non-Masking Interrupt) generates an NMI to halt system
operation. An NMI sends a high-level interrupt to the operating
system, which causes the system to halt operation to allow for critical
diagnostic or troubleshooting activities.
–
Graceful Shutdown attempts to cleanly shutdown the operating
system, then powers off the system. Graceful shutdown requires an
ACPI (Advanced Configuration and Power Interface)-aware operating
system, which allows for system directed power management.
–
Reset System (warm boot) reboots the system without powering off.
This option is disabled if the system is already powered off.
–
Power Cycle System (cold boot) powers off and then reboots the system.
This option is disabled if the system is already powered off.

racadm serveraction <action>
where <action> is powerup, powerdown, powercycle, hardreset,
or powerstatus.
