Abstract
The present invention relates to an auto-restore method for a powered device by using a computer device to build a detecting/responding packet in an Ethernet exchanger, and the Ethernet exchange can mutually transmit the packet with the powered device. If the Ethernet exchanger fails to receive a responding packet from the powered device in the predetermined time and the predetermined value, the Ethernet exchanger will terminate power supply by the Ethernet and reset the powered device, and the powered device will be restored automatically accordingly. If the powered device still cannot function normally after few times of reset, the Ethernet exchanger will shutdown the power supplied by the Ethernet and transmits an alarm signal to the computer device. Thus not only the consumption of the system and safety risk are reduced, but also promptly maintained, to increase the reliability, and save the supervision time of the operator and the cost of onsite maintenance. Besides, the prompt maintenance can also reduce the possible damage occurred during the breakdown of the powered device.
