HOT SWAP SYSTEM AND ELECTRONIC DEVICE UTILIZING THE SAME

摘要

A hot swap system applied in an electronic device includes a plurality of expansion cards and a plurality of electronic components coupled to the expansion cards. Each of the expansion cards includes an expansion chip, a time delay unit, and a switch unit. The time delay unit is electrically coupled to the expansion chip, and outputs a delay signal to the expansion chip to control the expansion chip not operate within a preset time. The switch unit can operate and transmit signal between the corresponding expansion card and the plurality of electronic components after preset time. Therefore, the hot swap system can operate normally, even when one of the expansion cards is inserted suddenly.
