H801SCUV Board Description

H801SCUV Board Description

The H801SCUV board is a super control unit board. It is the core of the system control and service switching and aggregation. The H801SCUV 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 10GE/20GE channel. In this manner, the H801SCUV board configures, manages, and controls the device, and also implements the simple route protocol functions.

Functional Specifications

Please refer to "SCU boards Comparison".

Technical Specifications

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

Working Principle

Figure 3-20  Working principle of the H801SCUV board

The basic working principle of the H801SCUV board is as follows:
  • The control module manages the entire board and the service boards, and communicates with the fan tray through the extended serial port. In addition, the control module can be configured with a built-in CF card to expand its storage space.
  • The logic module implements the logic 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 10GE port and the 20GE port to switch and aggregate services at Layer 2 or Layer 3.
    • Providing four 10GE ports for upstream transmission using ports on the front panel
    • Providing two 10GE ports for each upstream boards in upstream transmission
    • Providing 16 10GE/20GE ports for implementing 10GE/20GE switching on each service board
    • Providing two 20GE ports for load sharing with the standby control board
