Abstract: A method of monitoring a clock signal of a server is provided. The server includes a phase-locked loop (PLL), a baseboard management controller (BMC), and a light emitting unit. The method includes steps of: A) the server executing a time synchronization service to obtain a synchronization mode that the PLL is operating in, where the synchronization mode is one of a free-run mode, a locked mode, and a holdover mode; B) the server updating the synchronization mode to the BMC when executing the time synchronization service; and C) the BMC storing the synchronization mode and controlling the light emitting unit to display in one of a plurality of displaying manners that corresponds to the synchronization mode.
