operating system does not run, and all core logic except for the service processor
(also called the baseboard management controller) is shut down; however, the
server can respond to requests from the service processor, such as a remote
request to turn on the server. The power-on LED flashes to indicate that the server

v If a power failure occurs while the server is turned on, the server will restart
