Specifically, when the monitored pulse signal is a periodic signal, the first baseboard management controller is judged to be in a normal working state; and when the monitored pulse signal is abnormal, namely the pulse signal is a non-periodic signal or cannot be monitored, judging that the first substrate management controller fails.

When the first substrate pulse processor is judged to be invalid, the singlechip outputs a high level and a low level to an alternative gate to switch between the first substrate management controller and the second substrate management controller, so that the second substrate management controller is selected as a working substrate management controller, and the server can work normally.
