A network device for generating dying gasp signals includes an interrupt generating circuit, an external connecting circuit for connecting to another network device or a network, an internal processing circuit, a capacitor and a switch circuit. The interrupt generating circuit generates interrupt signals when the network device is without power. The internal processing circuit connected to the interrupt generating circuit, generates dying gasp signals according to the interrupt signals, and includes an input end. The switch circuit includes a first input end connected to the interrupt generating circuit, a second input end connected to the input end of the internal processing circuit and an output end connected to the external connecting circuit. The output end is connected to the external connecting circuit. The capacitor has one end connected to the input end of the internal processing circuit and the second input end of the switch circuit, and another end grounded.
