Active warning device for server and warning method thereof

摘要

The present disclosure provides an active warning device for server and the warning method thereof. The active warning device is applied to a server. When a control module in the server is departing from a midplane board, the active warning device can provide warning actively. Thereby, a user can notice that the control module is been drawing out of the server and then uses his both hands to support it for preventing tilt, fall, and hence damage of the control module.

1. An active warning device, applied to a server including a midplane board and at least a control module connected to said midplane board, comprising:
at least a reflector, disposed in said corresponding control module; at least a sensor, disposed on said midplane board, corresponding to said reflector, and connected electrically to a multiplexer of said midplane board; and an alarm, disposed on said midplane board, and connected electrically to said multiplexer of said midplane board; where when said control module departs from said midplane board, said sensor transmits energy to said reflector; said reflector reflects said energy; said sensor receives said reflected energy and produces a sensing signal; said sensor transmits said sensing signal to said multiplexer; said multiplexer calculates a distance between said control module and said midplane board according to said sensing signal, and compares said distance with a length of said control module; said multiplexer produces a warning signal according to said distance while said distance is smaller than said length of said control module, and said multiplexer transmits said warning signal to said alarm; and said alarm produces a warning sound according to said warning signal; wherein said step of comparing the distance between said control module and said midplane board with the length of said control module further comprises a step of judging the distance between said control module and said midplane board is greater than the length of said control module, a stop signal is produced and said alarm stops producing said warning sound according to said stop signal.
