The basic working principle of the H801X2CS board is as follows:
l The control module reports the status of and manufacturing information about the board,
and provides the interface information. The control module also manages the modules on
the board, and processes alarms.
l The interface module provides two 10GE ports.
l The synchronization Ethernet clock module extracts clock signals from the 10GE
signals, and synchronizes the 8 kHz clock of the control board with the clock signals.
l The power module supplies power to other functional modules of the board.
l The clock module provides clock signals for other functional modules of the board.
