The power button and LED allows you to manually take a server temporarily out of service but leave it
in a state where it can be restarted quickly, or to bring it back into service. If the desired power state for
a service profile associated with a blade server or an integrated rack-mount server is set to "off", using
the power button or Cisco UCS Manager to reset the server will cause the desired power state of the
server to become out of sync with the actual power state and the server may unexpected shutdown at a
later time. To safely reboot a server from a power-down state, use the Boot Server action in Cisco UCS
Manager.
