H801ETHA Board Description

H801ETHA Board Description

This topic covers the working principle, front panel, port, daughter board, and specifications of the H801ETHA board.

Functional Specifications

Please refer to "Ethernet Service Access Boards Comparison".

Technical Specifications

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

Working Principle

Figure 3-54 illustrates the working principle of the H801ETHA board.

Figure 3-54  Working principle of the H801ETHA board

The basic working principle of the H801ETHA board is as follows:

  • The control module loads board software, manages and controls board running, and reads information such as slot ID, version number, and board type.
  • The interface module includes the daughter board connector and provides eight GE ports.
  • The switching module completes line rate switching for Ethernet packets.
  • The power module supplies power to other functional modules of the board.
  • The clock module provides working clock for functional modules on the board.

The service processing is as follows:

  • In the downstream direction, the control board sends service data through the backplane connector to the switching module for line-rate switching of the Ethernet packets. The daughter board then implements service cascading.
  • In the upstream direction, service data is sent to the switching module through the daughter board, and then to the control board through the backplane.

Front Panel Port
