The control module loads the board software, controls the running of the board, and
manages the entire board.
The protection module protects and isolates the board from lightning strikes. The DC
block isolates the direct current. The protector protects the high voltage.
The forwarding module processes the signals. After being processed by the control
module, the signals are transmitted to the backplane bus through the interface of the
backplane.
The interface module inputs, outputs, and converts the signals.
The power module supplies power to each functional module of the board.
The clock module provides clock signals for each functional module of the board.
