Description
Technical Field

With the rapid development of the fields of mass data storage, data mining, image and video intelligent analysis and the like, the market demand of the server is gradually expanding. Besides pursuing high-quality services providing efficient and accurate powerful data processing and storage for clients through upgrading of software and hardware of the server, server manufacturers need to pour more human-friendly elements in server products, such as providing friendly human-computer interaction interfaces.
The front panel of the conventional server, which is one of the human-computer interaction interfaces, is only to simply reserve a power key PWR _ BTN/reset key RST _ BTN and basic hardware interfaces such as an indicator light, an ID indicator light, a VGA (Video Graphics Array), and a USB. However, the obvious disadvantage of this scheme is that if software and hardware faults such as a hang machine occur during the starting or running process of the server, the problem cannot be quickly located through an 80h Port of a BIOS (Basic Input Output System).
In addition, in the design scheme of the front panel of the dual-server node, which is widely applied in the server market at present, basic interfaces of the two server nodes, such as PWR _ BTN, RST _ BTN, VGA, USB, and the like, are usually integrated on the same PCB substrate through hardware circuits. However, the main problem of the above solution is that 2 sets of hardware circuits including buttons, VGA, USB, etc. are required, and the limited front panel occupies more space, and the economic cost is relatively high. Moreover, only a VGA interface is provided, which causes certain trouble to the server debugging and operation and maintenance stages, and when software and hardware faults such as hang machine occur in the server starting and operation processes, the information can be simply analyzed through the VGA, the complexity of the bottom layer drive design needs to be increased, and the operation state of the server cannot be effectively monitored and timely fed back to the research, development and operation and maintenance engineers. Especially when the VGA black screen problem is met, the operation and maintenance engineer puts the tie under the policy.
