Abstract: A network switch and a transceiver restart method thereof are provided. The network switch is configured to connect to a transceiver to transmit and receive data packets through the transceiver. The network switch includes a power control circuit and a processor. The power control circuit is controlled to provide electrical power to the transceiver. The processor determines whether the transceiver is in an abnormal state. In response to determining that the transceiver is in the abnormal state, the processor first controls the power control circuit to stop providing the electrical power to the transceiver, and then controls the power control circuit to re-provide the electrical power to the transceiver.

Abstract: A heat dissipation device adapted to dissipate heat of a heat source in an electronic system. The heat dissipation device includes a thermally conductive plastic shell and a fluid. The thermally conductive plastic shell has at least one sealed accommodation space. The fluid completely fills the at least one sealed accommodation space of the thermally conductive plastic shell.
