The H801X2CS board supports the following functions:

• Two 10GE upstream ports
• 10GE synchronous Ethernet

Working Principle

Figure 2 Working principle of the H801X2CS board 

The basic working principle of the H801X2CS board is as follows:

• The control module reports the status and manufacture information about the board, and provides interface information. The control module also manages other functional modules on the board and processes alarms.
• The interface module provides two 10GE ports.
• The synchronous Ethernet clock module extracts clock signals from the 10GE signals and synchronizes the 8 kHz clock of the control board with the clock signals.
• 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.

Front Panel
