Abstract

The embodiment of the invention discloses a circuit of a clock plate capable of achieving hot plugging and unplugging and a control method of the circuit. The circuit comprises the clock plate, the clock plate is connected with an IO plate through an M.2 interface, the circuit further comprises a CPLD control circuit on the IO plate, and the CPLD control circuit obtains an in-place signal and electrifying conditions of the clock plate and controls hot plugging or hot unplugging of the clock plate in combination with the state of a hot plugging and unplugging button. On the condition that the system is normally run, the clock plate is subjected to hot plugging and unplugging, a whole operating system cannot be influenced, the operation is simple, and loss caused when a user closes the operating system of a server is lowered.

Description

technical field [0001] The invention relates to the technical field of server clock boards, in particular to a hot-swappable clock board circuit and a control method thereof. Background technique [0002] With the continuous improvement of server functions, higher and higher requirements are put forward for server performance. In the design of the high-end server on the new platform, in order to increase the stability of the system and ensure that the board card can be taken out or replaced without cutting off the power supply, so as to improve the system's ability to recover from disasters in time, expandability and flexibility, etc., it is the server's R & D focus. [0003] For the control and hot-swapping of the clock board, the hot-swapping operation of the clock board can only be performed in the current server when the system is powered off. Especially when the clock board fails to be replaced during use, cutting off the system power supply is not only complicated. ,...
