Huawei LST7MPUE0001 (S12700E main control unit E)

Main control boards are essential components for switch operation. Each switch requires one or two boards—installed in either of the dedicated slots. When two boards are used, they operate in hot standby mode, providing redundancy and enhancing system reliability. The active and standby boards continuously monitor each other. If the active board fails, the standby instantly takes over to maintain seamless network operation and ensure uninterrupted services in mission-critical environments.
