The engine board is a type of main control board.
In the architecture of network equipment, the main control board is one of the core components of network equipment and is responsible for the control and management of the entire device. The engine board, as a kind of main control board, is usually located in the high-end aggregation or core switch. Its function is similar to the main control board, and it is responsible for the control and data processing of the switch. An engine board consists of several key components, including the chassis, engine board (main control board), cable card or service board, fan module, power module, and in some cases, an independent switch SFU. These components work together to ensure the reliability and high performance of the switch, while providing good scalability, making the frame switch suitable for the core location of the network .
In addition, the main control board is also used in non-network devices such as smart cars, where the "master" status usually refers to the master main control board, and the "slave" indicates the standby main control board . This further demonstrates the central role of the main control board in different devices and systems.
In summary, the engine board, as a form of the main control board, plays a crucial role in the network equipment, responsible for the control and management of the equipment, to ensure the reliability and high performance of the equipment.
