Abstract
An apparatus for use in a computer has a network interface subsystem having power applied thereto when power is removed from other components of the computer. A receiver in the network interface subsystem receives a packet directed to the computer from the network, and in response to receipt of a selected packet, restores power to the other components of the computer. Upon restoration of power to the other components of the computer, a signalling device reports status of at least one of the other components of the computer to the network interface subsystem. A transmitter in the network interface subsystem sends, in response to the signalling device, a status packet onto the network giving a status of the computer in the event that a component is not functional, following restoration of power to the other components of the computer. The computer has a processor which executes a self test upon restoration of power to the processor, and a self test signalling device to signal to the network interface subsystem the results of the self test, to initiate transmission of a status packet by the network interface onto the network in the event that the computer fails the self test. The sign…
