H801MCUD1 Board Description

H801MCUD1 Board Description

The H801MCUD1 board is a mini control unit board. It is the core of the system control and service switching and aggregation. The H801MCUD1 board can also function as the management and control core of the integrated network management system (NMS). It communicates with service boards about the key management and control information through the master/slave serial port and inband GE/10GE channel. In this manner, the H801MCUD1 board configures, manages, and controls the device, and also implements the simple route protocol functions.

Functional Specifications

Please refer to "MCU boards Comparison".

Technical Specifications

Please refer to "Power Consumption and Maximum Frame Size of Boards".

Working Principle

Figure 3-22  Working principle of the H801MCUD1 board

The basic working principles of the H801MCUD1 board are as follows:

  • The control module manages the entire board and the service boards.
  • The logical module achieves the logical control and stratum-3 clock functions.
  • The power module supplies power to other functional modules of the board.
  • The clock module provides clock signals for other functional modules of the board.
  • The switching module provides the GE port and the 10GE port to switch and aggregate services at Layer 2 or Layer 3.
    • Providing two GE/10GE ports or two GE ports for upstream transmission of the upstream port on the front panel
    • Providing two GE/10GE ports for implementing GE/10GE switching on each service board

Front Panel Port
