Abstract

An information processing system includes a modem communicating with a remote console through a telephone line, an information processing apparatus communicating with the remote console through the modem, a service processor, a power supply continuously supplying power to the modem and the service processor, a power supply supplying power to the information processing apparatus according to commands from the service processor, and a switch connecting the modem to the service processor or the information processing apparatus in accordance with a switching signal from the service processor. The service processor controls the switch to connect the modem to the service processor when the information processing apparatus power supply is in the off state. The service processor outputs a power-on command when the service processor receives a power-on request of the information processing apparatus power supply from the remote console through the telephone line and the modem and the switch connects the modem to the information processing apparatus when the execution of the power-on command is completed.
