Abstract
The remote power On devices used for powering a system from a remote console, to restart the system after a power failure. The remote console is connected to the system through switched network and autoanswer modem. When the connection is established the ring indicator signal of the modem interface is provided to the power control system controlling the power distribution in system. In response to this signal, the system service processor is powered on so that it is able to send messages to console inviting an operator to enter a password authorizing the general power on of the system. The password entered by the operator is sent to processor, checked and if it is correct the general power on of the system occurs. If not, the function is cancelled. In addition, the function may be inhibited at the remote system. This insures that the remote powering function is performed safely.
