Description

Control system in server and bridge board in control system

The present invention relates to a control system in a server and a bridge board in the control system, and more particularly to a control system and a bridge board in a server that detect potential signals and output working power to a motherboard.

In recent years, the popularity of smart terminal devices, the increasing demand for cloud equipment, and the advancement of technologies such as big data and artificial intelligence have led to rapid growth in server production and an increase in demand. In terms of server use, due to inflation, rising energy costs and longer delivery times for new servers, servers are facing challenges in cost and availability. In addition, high energy efficiency and the difficulty in procuring certain components have caused many companies to consider how to solve the current problems.

In addition to upgrading memory and storage, there are other steps you can take to extend the life of your server. Performing regular maintenance steps may seem simple to many, but it is no less important. For example, cleaning the server, checking for dust accumulation, and updating server software and drivers will improve performance and life.

However, the above-mentioned regular maintenance can only be a visible external maintenance measure. How to truly extend the life of the electrical components in the hardware equipment is the root problem that deserves more attention and improvement.

In the past, the motherboard and daughterboard in the server were electrically connected through cable routing, but the cable routing connection end was often not connected properly due to loose fixation or detachment, resulting in unstable signals or poor signal quality, which caused the system to power on and off multiple times in a short period of time, which may damage the electrical components on the daughterboard or significantly reduce the service life. In addition, if there is a need to replace the motherboard, the entire system needs to be powered off before replacement, which brings inconvenience to use. Therefore, the industry expects the design of hot-swappable motherboards with power on.

Therefore, in order to make the server system more stable and solve the problems of extending the life of its components, the main purpose of this invention is to provide a control system in the server and a bridge board in the control system. It is necessary to develop a more ideal technical method to solve the above problems.

In view of the various problems described in the prior art, the main purpose of the present invention is to provide a control system in a sweep server and a bridge board in the control system to solve the problems in the prior art.

This invention is to solve the problems of the previous technology. The necessary technical means adopted is to provide a control system in the server and a bridge board in the control system. Through the technology and hardware equipment provided by the control system and the bridge board of the present invention, the convenience of use can be optimized and the product cycle of the use of electronic components can be extended.

Another purpose of the present invention is to provide a control system in a server and a bridge board in the control system to ensure that various carrier boards such as motherboards and daughterboards in the server are connected to control the power output to avoid damage to electronic components and reduce their service life.

Among them, when the third connector is plugged into the first connector and the fourth connector is plugged into the second connector, the AC pull-up power supply unit detects that the potential signal on the line where the third connector is electrically connected to the first cable connector is pulled low, and then the bridge board will output working power to the motherboard.

To further explain, in the aforementioned control system, the bridge board will output working power to the motherboard only after the AC pull-up power unit detects that the potential signal on the trace of the third connector electrically connected to the first cable connector is pulled low. The bridge board will output working power to the motherboard only after the complex programmable logic element controls the bridge board.

It is further explained that when the AC pull-up power supply unit detects that the potential signal on the trace of the third connector electrically connected to the first cable connector is pulled low, the complex programmable logic element will delay for a predetermined time before controlling the bridge board to output working power to the motherboard, wherein the predetermined time can be 100 milliseconds.

When the third connector is not plugged into the first connector or the fourth connector is not plugged into the second connector, the AC pull-up power supply unit detects that the potential signal on the line where the third connector is electrically connected to the first cable connector is pulled high, and the bridge board is prohibited from outputting working power to the motherboard.

To continue, when the bridge board outputs working power to the motherboard, the motherboard can be directly hot-swapped from the bridge board without disconnecting the working power.

Through the design of the motherboard, the bridge board, and the daughterboard, the various carrier boards in the system can be more stably connected to avoid damage to internal electronic components caused by power being turned on in the case of poor connection, thereby extending the service life of the components. In addition, the above circuit design does not require the entire system to be powered off before replacing the motherboard, but allows the motherboard to be hot-swapped while powered on.
