ABSTRACT:
Described is a system which includes at least one computer system connected to a main computer system via a data transmission network. The at least one computer system has a network connector for communicating data with the main computer. The network connector is supplied with auxiliary power and is operative to communicate with the main computer regardless of whether the at least one computer system is in a normal operating state. The main computer includes a program for detecting when the at least one computer system has been disconnected from the data transmission network. The program sends a first packet to the at least one computer system via the network. The at least one computer system is operative to receive the first packet and respond by sending a second packet to the main computer. The second packet includes data which specifically identifies the at least one computer system.
