Abstract
A multi-state recognition device of a server blade system is provided. The multi-state recognition device comprises a logic circuit set for receiving a system state signal to control a multi-color LED set, and the multi-color LED set which illustrates the current sate of the blade server. The multi-state recognition device of the blade server receives plural signals outputted by the blade server and plural signals outputted by the system management unit. The blade server, the system management unit, and the multi-state recognition device all receive a main power source signal. The multi-state recognition device comprises a logic circuit set and a multi-color LED set, wherein the logic circuit set controls the multi-color LED set according to the plural signals outputted by the blade server and the plural signals outputted by the system management unit, so that the multi-color LED set generates various light signal states.
