If the Ethernet exchanger fails to receive a responding packet from the power device in the predetermined time and the predetermined value, the Ethernet exchanger will terminate power supply by the Ethernet and reset the power device, and the power device will be restored automatically accordingly. If the power 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 power device. ## Claims ### Claim 1 An auto-restore method for a power device, comprising an Ethernet exchanger and at least one power device; said Ethernet exchanger being connected to a computer device building a detecting/responding packet protocol in said Ethernet exchanger; said Ethernet exchanger comprising a CPU having a memory, and said CPU being connected to an Ethernet power control unit connected to said power device through an Ethernet interface; the auto-restore method comprising: (A) starting the auto-restore method; (B) judging whether a detection execution command transmitted from said computer device by said CPU, wherein if it is judged that no detection execution command is transmitted from said computer device, the procedure returns to step (A); otherwise, the procedure proceeds to step (C); (C) transmitting a detecting packet to said power device through said Ethernet interface by using said CPU; (D) judging whether a responding packet transmitted from said power device through said Ethernet interface is received by using said CPU, wherein if it is judged that said responding packet transmitted from said power device through said Ethernet interface is received, the procedure proceeds to step (E); otherwise, the procedure proceeds to step (F); (E) renewing detection information recorded in said memory by using said CPU, and the procedure returns to step (C); (F) increasing a non-responding record of said power device recorded in said memory; (G) judging whether said non-responding record of said power device stored in said memory is higher than an internal predetermined non-responding value in said memory by using said CPU, wherein if it is judged that said non-responding record of said power device stored in said memory is lower than an internal predetermined non-responding value in said memory, the procedure proceeds to step (C), otherwise the procedure proceeds to step (H); (H) judging whether a reset record of said power device stored in said memory is higher than an internal predetermined reset value in said memory by using said CPU, wherein if it is judged that said responding record of said power device stored in said memory is lower than said internal predetermined reset value in said memory, the procedure proceeds to step (I), otherwise the procedure proceeds to step (L); (I) transmitting a power shutdown signal to said Ethernet power control unit by using said CPU, wherein said Ethernet power control unit disconnects power supplied by said Ethernet, and said Ethernet exchanger stops transmitting power to said power device to further shutdown said power device; (J) transmitting a power activation signal to said Ethernet power control unit after a predetermined time by using said CPU, wherein said Ethernet exchanger continues to supply power to said power device and said power device will be reset; (K) increasing a reset record in said memory by using said CPU, and the procedure proceeds to step (C); (L) transmitting a power shutdown signal to said Ethernet power control unit by using said CPU, wherein said Ethernet power control unit disconnects power supplied by said Ethernet, and said Ethernet exchanger stops transmitting power to said power device; and (M) ending the auto-restore method. ### Claim 2 (depends on 1) An auto-restore method for a power device according to claim 1, wherein when said CPU judges a reset record of said power device stored in said memory is higher than an internal predetermined reset value in said memory, and said CPU transmits an alarm signal to said computer device. ### Claim 3 (depends on 2) An auto-restore method for a power device according to claim 2, wherein said alarm signal of CPU of said Ethernet exchanger transmitted to said computer device can be as a electronic Email, a SNMP Trap or an active message. ### Claim 4 (depends on 1) An auto-restore method for a power device according to claim 1, wherein said power device can be a notebook computer, an industrial computer, a desktop computer, a server, an internet phone, a base station, a webcam or a hub. ### Claim 5 (depends on 1) An auto-restore method for a power device according to claim 1, wherein said Ethernet interface can be an Ethernet connecting component. ### Claim 6 (depends on 1) An auto-restore method for a power device according to claim 1, wherein said computer device comprises a graphic operation interface comprising information including a selection of activating functions of detecting and repairing an execution status of said external power device, an internet protocol of said power device or a time record of repeating detection. ### Claim 7 (depends on 1) An auto-restore method for a power device according to claim 1, wherein said detecting/responding packet protocol can be a packet internet groper (ping). ### Claim 8 (depends on 1) An auto-restore method for a power device according to claim 1, wherein said detection information comprises a non-responding record and a reset record of said power device.
