H uawei S7703/S7703 engine main control board ES1D2MCUD000 Main Control Unit D Function The ES1D2MCUD000 single board is the main control unit board of S7703/S7703 PoE, which integrates the main control unit and the system maintenance unit. The main implementation of the following functions: provides an out-of-band communication channel between the entire system board. To provide system operation status monitoring function,ES1D2MCUD000 is responsible for regularly collecting the operation data of each unit of the system, generating control information according to the operating status of each unit, such as detecting the presence of each single board, controlling the operating status of the switching network, port switching, forwarding engine reset and fan acceleration. Provide device management, maintenance and other functions, through the ES1D2MCUD000 to provide external management interface (serial port, network port), as a proxy for network management software. Provide data configuration function, system configuration data, startup files, billing information, upgrade software and system operation log information are placed on the ES1D2MCUD000. Functions and features of the ES1D2MCUD000 Function Description Basic functionality The ES1D2MCUD000 single board is the main control unit board of S7703/S7703 PoE, which integrates the main control unit and the system maintenance unit. Memory 2GB Flash Nand flash:2GB Redundant backups Backing the main control board is a mandatory single board, and each switch can be configured with one or two main control boards. when equipped with a master board, it can be installed in any main control board slot on the switch. when configuring two main control boards, the main control board supports the hot backup function, which improves the reliability of the switch: the main control board monitors each other, and when the main control board fails, the standby main control board will automatically be upgraded to the main control board to ensure that the service is not interrupted. Hot-swappable Backing Before unplugging the primary ES1D2MCUD000, the primary standby needs to be reversed.
