H801MCUD Board Description

H801MCUD Board Description

The H801MCUD board is a mini control unit board. It is the core of the system control and service switching and aggregation. The H801MCUD 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 H801MCUD 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 3-21  Working principle of the H801MCUD board

The basic working principle of the H801MCUD board is as follows:

  • The control module manages the entire board and the service boards.
  • The logic module implements logic control.
  • 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 four GE ports for transmitting traffic upstream
    • Providing 2 GE/10GE ports for implementing GE/10GE switching on each service board
    • Providing one 10GE port for load sharing with the standby control board
