A computer management system attains, through one line, the uniform and steady system management through an agent such as monitoring of fault and power control in a computer connected by LAN as well as a public line, and system management for an off-state of the computer or abnormal operation state of the computer such as remote power control and notice and diagnosis of critical fault by the direct connection with a service processor through the line. The system includes an agent connected to a computer to be managed for executing instructions on the computer to be managed, a service processor board having a processor independent from the computer to be managed for monitoring fault in the computer to be managed and controlling power of the computer to be managed, a manager for executing instructions on a management computer and conducting controls such as fault monitoring and power control through the agent over a network including a public line, and a service processor manager directly connected to the service processor for conducting remote power-on and receiving and diagnosing critical fault. The service processor and the service processor manager are provided with switching circuits for switching an asynchronous interface for remotely connecting to the computer to be managed and an asynchronous interface for directly connecting to a local processor of the service processor.

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.
