Abstract

The invention provides a hot plug control method and device, a retimer, an expansion card and electronic equipment. The hot plug control method comprises the steps that data are received from pluggable equipment through a second end, the data are sent to an RC through a first end, and the RC supports hot plug; sending a detection signal to the second end to detect the connection state of the pluggable device and the second end; and when the pluggable equipment is detected to be thermally separated from the second end, stopping sending the data to the RC, and sending a first control signal to the RC, so that the RC processes an abnormal state of stopping sending the data according to the first control signal. According to the hot plug control method provided by the invention, the hot plug of the pluggable equipment can be realized without an in-place signal, so that the problem that the hot plug of the equipment cannot be realized under the condition of no in-place signal can be avoided.

Description

technical field [0001] The present application relates to a control method, and in particular, to a hot-swap control method, device, retimer, expansion card and electronic equipment. Background technique [0002] With the continuous development of technology, more and more server manufacturers use Retimer to provide users with scalable high-performance PCIe (Peripheral Component Interconnect express, high-speed serial computer expansion bus) interconnect solutions. In the process of using the Retimer, devices such as NVME (Non-Volatile Memoryexpress, non-volatile memory bus) SSD (Solid State Disk, solid-state drive), GPU BOX (graphics processor box) and other devices need to be hot-swapped. However, the inventor found in practical applications that the related technology mainly uses the in-position signal to realize hot-plugging. If the system does not consider the in-position signal in the design, it may cause the device to fail to achieve hot-plugging, and the device needs...
