Abstract: An electrical module, a backplane for the electrical module, and a method of replacing a fuse for the electrical module. The electrical module includes a circuit board which has a power input port for inputting electric power to electrically drive an external device coupled to the electrical module. The electrical module also includes a fuse holder electrically coupled to the power input port and adapted to receive a fuse. A fuse detecting circuit is arranged on the circuit board and electrically coupled to the fuse via the fuse holder to detect a status of the fuse. An output port is arranged on the circuit board and coupled to the fuse detecting circuit to at least output detecting signals about the status of the fuse to a controller.
